Optimisation of the deposition parameters of thick atmospheric plasma spray coatings

Abstract

Plasma spray process is one of the most versatile thermal spray deposition processes. There are great number of parameters that influence the quality and characteristic of deposited coating and their values must be defined precisely for each type of coating and used equipment particularly. A review of technology developed for deposition of ferrous-based powder spray (Fe-1.3Cr-1.5Mn-1.2C-0.3Ni, wt. %) on flat Al-Si alloy substrate surfaces is presented in this paper. Possible problems that may occur before and during the deposition process were pointed out as well as adequate solutions of those problems.
