The research involves using Epoxy ,Unsaturated Polyester and Novolac resins ;they were needed to prepare ternary polymer blends; wear resistance including change load applied, sliding velocity, using these resins with that ratios as (80%/10%/10%). Also hardness (shore) were study before and after immersing in (NaOH,HCl) solutions with(0.5) normality . In general the wear resistance was increased with the load applied (20N) and with immersion time. The effect of base solution was larger than that of the acid. Shore hardness was decreased after immersing in solution.
