Study on Preparation of Plasma Nitride Coating on the Surface of Cemented Carbide Blade and its Wear Resistance AITranslate
Abstract AITranslate
Plasma nitride coating was prepared on the surface of cemented carbide blade under the conditions of nitrogen atmosphere and high pressure. The phase composition of the coating was characterized by XRD,its micro-hardness was tested by a micro-hardness tester, and its microstructure on surface and sec- tion was observed by SEM. Wear resistance of the coating was evaluated by contrasting friction coefficient between cemented carbide sample and coated sample. The wear mechanism of cemented carbide and coated sample was studied based on friction and wear surface morphology. The results show that the coating was mainly composed of TiN of about 5 pm layer thickness. The coating is tightly bonded to the substrate with- out obvious gap and crack. The friction coefficient of cemented carbide substrate is about 0.4 with relative- ly large fluctuation,while the coating has stable friction coefficient around 0.2. Plasma nitride coating on cemented carbide surface can effectively improve the wear resistance of the substrate.
