چکیده مقاله
In the present study, the effect of dissolution of tungsten carbide WC particles on the erosion wear resistance of hard coatings created by oxy acetylene welding process had been investigated Higher preheating temperature was shown to dissolve tungsten carbide WC reinforcing particles and eliminate their high erosion wear resistance Also, the results of x ray diffraction clearly showed a significant reduction in the amount of tungsten carbide and the formation of brittle W2C phases resulting from its dissolution The hardness of the coating about 900 Hv was obtained in preheated specimen at the suitable temperature compared to preheated specimens at higher temperatures about 1300 Hv Excessive dissolution of tungsten carbide particles along with the formation of brittle W2C phase due to unfavorable preheating conditions led to a significant reduction 68% in erosion wear resistance
