30多年来,高质量的WC-Co涂层几乎都是使用爆炸喷涂方法实现的,美国的联合碳化物公司至今独家垄断着这一技术,承揽着世界范围的喷涂加工业务(详见本刊1986年第3期)。80年代以来,一种新的热喷涂方法——超音速火焰喷涂的出现引起了人们的注意,其发明人把这种方法称为Jet Kote。用这种方法喷涂的WC-Co涂层己经达到甚至超过爆炸喷涂层的质量,开始与爆炸喷涂相抗衡。在进行 For more than 30 years, almost all high-quality WC-Co coatings have been produced using explosive spraying methods. United Carbide Corporation of the United States has exclusively monopolized this technology so far and has been engaged in the world-wide spray coating business Year 3). Since the 1980s, a new thermal spraying method, the emergence of supersonic flame spraying, has drawn the attention of its inventors as Jet Kote. The WC-Co coating sprayed in this way has reached or exceeded the quality of the blast spray coating and started to compete with the blast spray. In progress
