STELLİT KAPLAMALI VALF YÜZEYLERİNİN ODA SICAKLIĞINDA VE 300 0C'DE ADHESİF AŞINMA DAVRANIŞININ BULANIK MANTIK YÖNTEMİ İLE ANALİZİ

In this study, 1.4718 coded steel surface, which is used especially in the manufacture of automotive valves, is coated with cobalt-based Stellite 1, Stellite F, Stellite 6, and Nickel 60 alloys by the TIG welding method. The samples coated with the specified welding parameters were abraded for 4400 meters on a metal abrasive disc under 10, 25, and 40 N loads, at room temperature and 300 0C. The weight losses of the samples were measured every 1100 meters, and their wear resistance was investigated. It has been determined that the experimental study results and fuzzy logic estimations overlap with each other, and fuzzy logic estimations can be used to determine the wear behavior in the intermediate values that were not tested.
