Modern Proficiency in Thermal Spray Coatings to Enhance Wear Resistance of Material

Abstract

Various techniques are employed to protect the material from degradation. As the wear is a surface phenomenon and occurs mostly at outer surfaces. Most industry segments, significant financial losses may be incurred due to accelerated wear of various components. In order to minimize the effects of mechanical wear and extend product life, thermal spray coating solutions introduced into production and is further developing them to meet even more demanding wear applications. Therefore it is more appropriate and economical to use surface engineering for making surface modifications. High-velocity oxy-fuel (HVOF) is one of the thermal spraying techniques known for providing hard, wear resistant and dense micro structured coatings. Applying coatings using thermal spray is an established industrial method for resurfacing metal parts. The process is characterized by simultaneously melting and transporting sprayed materials, usually metal or ceramics, onto parts. Now a day's High-velocity oxy-fuel (HVOF) spray coatings are gaining popularity due to exceptional hardness, wear resistance and cost effectiveness. In this paper some studies on Thermal sprayed wear resistant coatings have
