近几年来,利用钛、氮化钛及碳化钛作为表面镀层材料,以增加刀具及磨擦另件的抗磨损能力,取得了良好的效果,其中又以氮化钛效果最好。镀氮化钛的方法很多,已在应用的有化学方法、物理方法、电子蒸发法、离子轰击法及离子涂镀法等。其中又以近几年新发展起来的离子涂镀法优点最多,引起了人们的注意。氮化钛离子涂镀技术的主要机理是:将若干块金属钛悬挂于密闭室的四周,在密闭室的壁与金属钛之间,始终存在电弧放电。在电弧的局部高温作用下,固体金属钛直接变为蒸气。这一变为蒸气的过程,几乎是在瞬间完成的。并使钛离子获得了很大的能量。离子
In recent years, the use of titanium, titanium nitride and titanium carbide as the surface coating material, in order to increase the wear resistance of the tool and the friction piece, and achieved good results, of which the best effect of titanium nitride. Many methods of plating titanium nitride, has been used in chemical methods, physical methods, electronic evaporation method, ion bombardment and ion plating method. Among them, the newly developed ion plating method has the most advantages in recent years and has drawn people’s attention. Titanium nitride coating technology is the main mechanism is: a number of pieces of titanium suspended in airtight chamber around the room in the sealed chamber and titanium metal, there is always arcing. In the arc of the local high temperature, the solid titanium metal directly into steam. This process of vaporization is almost instantaneously completed. And titanium ions have gained a lot of energy. ion
