Abstract:

To research the wearing properties of coatings and surface engineering components, a new type high temperature abrasive wearing tester was introduced and its experimental evalwation was presented.It can be used to simulate and study the oxidation and abrasion interaction at elevated temperature.The influences of the testing temperature, load, time and three kinds of abrasive on high temperature wear property of coating were investigated by using this new apparatus.The experiment results show that this abrasive wearing tester is able to evaluate abrasive wearing property of coating at various temperature and various load.It has a simple structure that operates stably with good reliability.By using this abrasive wearing tester, it was found that the coating abrasive resistance of the coating varied significantly according to the testing temperature and testing load.
