Abstract

U radu su provedena ispitivanja triboloških i korozijskih svojstava austenitnog nehrđajućeg čelika X5CrNiMo 17-12-2 prevučenog prevlakom PACVD TiN na temperaturama 500℃, 520℃, 540℃, 560℃ uz vremena prevlačenja 6 i 8 sati. Na prevučnim uzorcima provedeno je određivanje debljine prevlake kalotetsom, ispitivanje adhezivnosti prevlake prema normi VDI 3198:1992, određivanje elektrokoemijskog potencijala, ispitivanje otpornosti na točkastu koroziju i ispitivanje otpornosti na mikroabraziju na kalotestu sa slobodno rotirajućom kuglicom obloženom suspenzijom s dijamantnim zrncima. Iz rezultata ispitivanja zaključeno je da se uz temperaturu PACVD postupka od 500℃ uz vrijeme prevlačenja od 6 ili 8 sati može postići najbolja otpornost trošenju i otpornost rupičastoj koroziji uz potrebu za budućom optimizacijom parametara kojom će se postići poboljšanje prionjivosti prevlake PACVD TiN na podlozi ispitivanog čelika X5CrNiMo 17-12-2.

Abstract (english)

Tribological and corrosion tests of austenitic stainless steel X5CrNiMo 17-12-2 coated with PACVD TiN at temperatures of 500℃, 520℃, 540℃, 560℃ with coating times of 6 and 8 hours were performed in this paper. On the coated samples, the thickness of the coating was determined with a calotest, the adhesion test of the coating according to the VDI 3198:1992 norm, the determination of the electrochemical potential, the test of resistance to pitting corrosion and the test of resistance to microabrasion on the calotest with a freely rotating ball coated with a suspension with diamond grains. From the test results, it was concluded that with a temperature of the PACVD process of 500℃ and a coating time of 6 or 8 hours, the best wear resistance and resistance to pitting corrosion can be achieved, with the need for future parameter optimization that will improve the adhesion of the PACVD TiN coating on the tested steel substrate.
