Abstract: Metallized coatings do represent special solution for ensuring wear resistance, good lubrication or, high corrosion protection characteristics of parts submitted to severe “working” condition. Some of the materials used in metallizing are represented by special alloyed steels. Usually, the resulted coatings need further machining, by turning or grinding. So, their surface roughness do represent an important parameter to be known or, rather, estimated by the values of process parameters values. This paper presents applied statistics methods used for determining surface roughness models as function of turning process parameters, such as: cutting speed, feed and depth, cutting tool wear and nose radius. The metallized materials studied are, conventionally called “soft steels”, due to their micro-hardness values, about 300-350 HV0.05.
