temperature effect on the properties of wear-resistant tungsten carbide coating

tungsten wire coating quality mainly depends on the spraying material and the heating and acceleration method. Particle speed had a great influence on coating quality, high particle velocity can make the coating quality is greatly improved. Supersonic flame spraying because of high particle impact velocity (610 ~ 1 060 m/s), makes the coating bond strength, hardness, density and wear resistance are improved. Preparation of the coating and using this technology
