WEAR EVALUATION OF AN AIS11020 STEEL COATED WITH PEEK

摘要

PEEK (Poly-ether-ether-ketone) coatings have been attracted interest from some industry sectors due to its good wear resistance. In this study the wear resistance of a AISI 1020 steel coated with PEEK it was compared with that the AISI 52100 steel quenched and tempered to a hardness of 60HRc. The wear tests were performed in a fixed-ball micro-wear machine, using three different loads in the dry condition and using a lubricant. It was found that the PEEK coating presented a better wear performance than the AISI 52100 steel in dry condition and a wear performance close to the lubricated AISI 52100 steel while the PEEK layer maintains its integrity. In the case of the lubricated tests, the AISI 52100 steel provided the best performance among the samples tested.
