摘要
金属陶瓷因既具备金属材料优异的强度、高温导热性和热稳定性,又具备陶瓷材料的耐高温、耐腐蚀等特性而广泛用于制造切削刀具。金属陶瓷耐磨性和硬度不足的问题限制了其应用范围,在其表面制备硬质涂层可以解决这一问题,但是涂层的结合强度弱,易剥落。介绍了硬质涂层的制备方法、涂层与基体结合强度的影响因素,阐述了提高硬质涂层结合强度的方法,最后对金属陶瓷表面硬质涂层的制备技术及结合强度的提高进行了展望。
Cermet is widely used in manufacturing cutting tools because of its excellent strength,high temperature thermal conductivity and thermal stability of metal materials,and high temperature resistance and corrosion resistance of ceramic materials.The lack of wear resistance and hardness of cermet limits its application range,which can be solved by preparing hard coating on its surface,but the bonding strength of the coating is weak,resulting in peeling off of the coating.The preparation method of the hard coating,the influencing factors on the bonding strength between the coating and the substrate are introduced,and the methods to improve the bonding strength of the hard coating are expounded.Finally,the preparation technique and the improvement of bonding strength of hard coating on cermet surface are prospected.
