金属的耐磨性,可以利用激光浸渍的方法改进。即用激光化基体材料表层,并把高抗磨碳化物粒子浸渍到(?)池中。以前的方法主要用10kW激光功率在真空中进行。本文给出了用1.5和2.5kW的激光功率在大气压下进行试验的结果。经激光浸渍的金属表层的耐磨性大大提高,比未处理的铝提高20～40倍,比淬火的碳钢提高了5～20倍。

The wear resistance of the metal can be improved by means of laser dipping. That is, the surface layer of the base material is laser-irradiated and the high-wear-resistant carbide particles are impregnated into the? The previous method mainly used 10kW laser power in vacuum. This paper presents the results of experiments carried out at 1.5 and 2.5 kW laser power at atmospheric pressure. The abrasion resistance of the laser-impregnated metal surface is greatly enhanced by 20 to 40 times more than untreated aluminum and 5 to 20 times more than quenched carbon steel.
