Effect of Plasma Spray Variables on Cu-Ni Coated A7075

Abstract: This paper discusses the effect of several variables in plasma spray method, namely; the flow rate, spray distance and power used on the mechanical properties of Cu-Ni coated A7075. All spraying techniques were designed using 23 factorial plans prior to the actual experiments. The produced coatings were characterised using a scanning electron microscopy (SEM). Morphological observation indicated that most sprayed particles were formed in splash shape splats. The effects of interactions between the response var… Show more

“…Satapathy [9]found that the use of plasma spraying on the surface of (Al, Cu, mild steel, stainless steel) with a red mud, makes the coatings possess good adhesion strength, hardness with reasonable porosity, erosion wear .Sahab [10]showed that the high temperature of flame permit ceramic materials such as Al 2 O 3 powder to be melted and sprayed toward substrate in producing a coating. Ammar et al [11]studied the effect of flame spray parameters(distance, roughness, temperature of substrate, thickness) on wear rate and found that the best distance is (150-200)mm, substrate temperature (200-300)°C, and thickness(0.15-0.5)mm gavethe lower rate of wear and the highest adhesion.…”
