The aim of this study is to improve wear resistance of the rasp parts which used in paper industry drying step by using thermal spraying coating techniques. Improving the wear resistance of coated rasp used in the paper industry with the development of a large part of the production process is automated, wasting paper will reduce, wear blasting damaging the paper will be blocked and frequent blasting replaced with production processes in line continuity will be provided. The main purpose of thermal spraying method is to produce wear resistant surfaces. Easy applicability, very low possibility of metallurgical changes and low distortion of coated parts due to low heat transfer to the substrate and salvation of worn parts are some of the practical advantages of this process. Plasma spray coating and powder flame spraying (spray powder fusing) techniques were used prevent wear of the steel substrates. The commercial feedstock powders in the mass fractions 75 % Cr2O3 (Metco 106)-25 %TiO2 (Metco 102) and Colmonoy 705 (Nickel-Base Hard Surfacing Alloy) powders were used as a coating powder. ASTM G65 Wear Test was used for evaluating abrasion resistance of the coatings.
