Laser shock peening without coating induced residual stress distribution, wettability characteristics and enhanced pitting corrosion resistance of austenitic stainless steel

In this research work, multiwall carbon nanotube (MWCNT) based nickel coating is prepared and deposited on unfinished metal made sewing needle by employing electrochemical process. The coating thickness was attained to 3 microns per 90 minutes. The microstructure, micro-hardness, friction and wear properties of the Nickel-MWCNTs coatings were investigated and discussed. The uniformity and presence of primary components in the coating layer were observed and confirmed through scanning electron microscope. The friction and wear behavior of the coated and uncoated samples were tested on a pin-on disc tester. The specific wear rate of the coated sewing needle is improved significantly than the uncoated sewing needle; the co-efficient of friction of the coated needle is reduced to 2.1. The surface roughness of the coatings was measured by employing portable surface roughness tester. The surface roughness Ra of the coated sample is improved to 0.095. The Vickers hardness of the coated needle is improved to 63 compared with the uncoated needle. © BEIESP.

In this report, we use Pearson and Spearmen methodologies for the real-time dataset of finding the data efficiency in the contact lenses selection dataset. In statistics, the Pearson coefficient of correlation, conjointly cited because the Pearson's r or Pearson product-moment coefficient of correlation could be alive of the linear dependence between two variables X and Y. It's a worth between +1 and -1 comprehensive, wherever one is a total positive linear correlation, zero isn't any linear correlation, and -1 is a total negative linear correlation. The Spearmen methodology is that the correlation methodologies utilized to spot the complexes between the various attributes in the dataset. Then we use Pearson and Spearmen method to determine the correlation between the attributes in the contact lenses selection dataset. © 2017 IEEE.

Low-stress mechanical properties of spacer fabrics are investigated from the six polyester warp-knitted spacer fabrics and have been tested on Kawabata instrument. Three different types of spacer fabrics with a thickness of 2, 3.1 and 4 mm were prepared using three different face layer structures, namely locknit, rhombic mesh and hexagonal net and the influences on fabric properties were studied. The fabric with secured locknit structure and higher fabric thickness shows the high values in the compression, bending and shear properties. However, in case of tensile strength, the fabric of open mesh structure with higher fabric thickness decreases the tensile properties. The 3.1 mm fabric thickness along with hexagonal net structure shows the fine response on compression properties and reasonable effects on the other low-stress mechanical properties. © 2016, © The Textile Institute and Informa UK Ltd 2016.

Sandwich structure of non-woven composite is produced by using a compressive hot pressing method. It is ranging from 2500 grams per square meter (gsm) to 3500 gsm. Composite sample is designed using Box and Behnken model. Considering 50–70% weight of jute fibre content with 30–50% weight of hollow conjugated polyester fibre, ideal thickness of the composites is maintained in the range from 4 to 5 mm. Thermal properties such as thermal conductivity, thermal resistance, thermal transmittance and thermal diffusivity were evaluated by considering three factors: weight of jute (A), weight of hollow conjugated polyester (B) and thickness of the composite (C). The thermal conductivity of the composite material is determined by heat flow meter method ASTM C518. Experiment result will help to make a suitable standardized panel composite for thermal insulation. It requires 3600 gsm 51/49 parts of contribution of jute/hollow conjugated polyester fibre with 5.0 mm thickness and 3200 gsm 76.5/23.5 parts of contribution of jute/hollow conjugated polyester fibre with 4.5 mm thickness of the composites. The composite weight of 3280 gsm shown optimized thermal responses, it was predicted from response surface method graph. Contribution of jute/hollow conjugated polyester fibre of 54/46 parts with 5.0 mm thickness would be considered to make standardized composite panel. Mostly air conditioning process reduces the energy cost spent for the thermal stability in indoor climate of dwellings. © 2015, © The Author(s) 2015.

Study of thermal properties of jute and hollow conjugated polyester fibre reinforced non-woven composite

The use of cushioned insoles has been recommended as a method to reduce the impact forces on feet associated with running. This study is used to determine the influence of insole structure and thickness on the permeability and conductivity properties of air and temperature. The insoles are constructed with warp-knitted polyester spacer fabrics with 3D construction and have good cushioning, permeability, and conductivity properties. The middle layer is made up of polyester monofilament yarn which decides the thickness of fabric, and the two outer surfaces of the fabric were made from polyester multifilament yarns which is a closed and open structure. The comfort properties of spacer fabric have been studied by measuring air permeability, water vapor permeability, and thermal properties with respect to fabric porosity. One-way analysis of variance is used to analyze the significant of fabric thickness and surface structures. The experimental result shows that the vertical gap of the two outer surface layers and the horizontal pore size of the face surface decide the permeability and conductivity properties of spacer fabrics. The fabric with higher porosity show high permeability of air and water vapor. Depending on the fabric thickness and structure, the 4-mm thickness of spacer fabric with locknit structure resulted in low air and water vapor permeability. It is found that the 3.1-mm thickness spacer fabric with hexagonal net structure proves to have good air and water vapor permeability and comparatively lower thermal conductivity. © 2014, © The Author(s) 2014.

Nickel-based multiwalled carbon nanotube (NiMWCNT) composite coatings were electrodeposited over the inner groove of an aluminim alloy rotor with ZnNi interlayer. The surface of the composite coating was investigated by X-ray diffraction and scanning electron microscopy. The hardness of the coating was determined by Vickers method. It was revealed that NiMWCNT composite coating has uniformity in thickness over the surface of the aluminim groove and also better particle distribution over the area. It was found that there was a significant improvement in the microhardness values of NiMWCNT composite coating than uncoated aluminum alloy rotor. In addition, the wear resistance of the composite coated increased nine times than the uncoated substrate. Thus, NiMWCNT composite coated aluminum alloy rotor can enhance the performance and life-time of the rotor in the textile industries. © IMechE 2015.

Nickelmultiwalled carbon nanotube composite coating on aluminum alloy rotor for textile industries

NiP-multiwall carbon nanotube composite coatings were deposited on a textile component at ∼4 μm thickness through electroless plating route. The composites were prepared by depositing four different concentrations of multiwall carbon nanotube (i.e. 100,200,300 and 400 mg L-1) in an electroless bath over four NiP substrates. The NiP-multiwall carbon nanotube composite coating was observed to have a remarkably lower surface roughness and higher micro-hardness - by about 50% in both cases - in comparison with the NiP electroless plated substrate without the incorporation of multiwall carbon nanotube. In addition to that, there was a 14% reduction in yarn to metal friction between the investigated cases. This particular enhancement was adduced to the addition of surfactant to the electrolytic bath. The superior homogeneity in the distribution of multiwall carbon nanotube in the nickel matrix and the formation of the Ni-C bond were also identified to drive the multiwall carbon nanotube towards much improved properties. © 2016 Institute of Materials, Minerals and Mining.
