ABRASIVE WEAR PROPERTIES OF PLASMA SPRAYED Y-PSZ COATED 6063-T6 ALUMINUM ALLOY

Abstract

Thermal spray methods and especially plasma spray method have an increasing importance and being widely used by industries. This method depends on the purpose of spraying powder based coating materials to a surface. Light alloys like aluminum alloys have some disadvantages like low mechanical strength and wear resistance Aim of this study is investigating the wear resistance behavior of coated and uncoated T6 heat treated 6063 Aluminum alloys. Coatings were made by plasma spray method and %8 Y-PSZ was used as coating material. Wear tests were done by pin-on-disc method with three different load parameters and results were discussed comparatively.
