The mechanical ball-rolling made the Ni P coatings crystallized in-situ during the coating process, thereby avoiding crystallization-induced cracking, which was observed during the crystallization of the amorphous Ni P coatings electroplated without mechanical assistance.
The main objective of the present work is to investigate the effect of TiVN on the microstructure, mechanical properties and tribological performance of the deposited TiVN/TiSiN coatings by regulating the bias voltage during the coating process.
A substrate heater raises the LN to about 400 °C before and during the coating process.
Flaws are pores or protuberances present in the coating surface formed during the coating process.
Substrate surface defects like holes and protuberances were not duplicated during the coating process.
XRD analysis showed that the carbides of Ti, Cr, or W were formed during the coating process.
The Cr(N,O) composition was varied by changing the O2/N2 flow ratios during the coating process.
However, the achievement of desired coating standards and improved properties of the as-deposited substrate largely depends upon rigid process control measures adopted during the coating process.
The consistency of the coating thickness depends on the stress distribution on the ITOF sensor, and the vertical alignment of the fiber during the coating process.
The final microspheres were treated by different catalyst concentrations, during the coating process, which resulted in the formation of diffused voids (a porous-like structure).
The defects generated during the coating process acted as preferential paths for diffusion of oxygen resulting in the oxidation of substrate ZIRLO™.
