The bond strength is a critical consideration for the plasma-sprayed NiCrBSi coatings. However, conventional methods testing of coatings always cost time and money. If there simple method that could predict prepared without destroying coatings, it would be significantly beneficial industrial applications. In this work, new was proposed based on total areas interfacial pores coating by plasma sp...

The strengthening hard phases TiN/C1-xNxTi were generated by in-situ solid-gas reaction in Ni-based composite coatings prepared using a plasma spray welding process to reinforce the wear resistance of the coatings. The microstructures and properties of the coatings were investigated. The results showed that the coatings mainly consisted of phases such as TiN, C1-xNxTi, TiC, etc. A small amount ...

The objectives of this research were to find an economical way of reducing porosities in the microstructure of coatings deposited by flame spraying technique on CK45 steel and also trying to increase their cohesive strength to the substrate, so that the overall wear properties of this type of coating can be improved. So several specimens from this steel coated with NiCrBSi powder under specific...

This work aims to propose an approach estimate the final surface roughness as a function of hardness ratio between coating and debris (Hpin/Hdebris = Hp/Hd) under lubricated conditions employing pin-on-disc configuration. Using this provides better understanding prediction lubrication regime (Stribeck Curve) compared with traditional that uses initial roughness. Our results demonstrate lower in...
