Surface Roughness Statistic Models of Metallized Coatings in Grinding Manufacturing System

Abstract:- Metallizing process has known a continuous extent, lately, because of the sprayed coatings’ intensive application into various industrial fields. Metallized coatings have very important wear or, corrosion resistance characteristics and, when used for repairing worn parts, the prescribed surface quality specifications can be obtained only by grinding, after thermal spraying. Statistic models of grinded surface roughness are useful, specially, for optimizing the machining process. For adequate and, faster measurements, a LabVIEW data acquisition system was used to obtain grinded surface roughness values and, for obtaining statistical models needed, specialized regression soft-ware was considered. Key-Words:- metallized coating, surface roughness, experiment design, regression analysis, statistic model
