采用超音速火焰喷涂（HVOF）方法制备了铜及铜钨复合涂层。经过初步优化的喷涂参数，涂层的各种组成，其结构，组成，机械，热，和电气性能进行了表征。HVOF技术能够产生相当致密的涂层，具有最小的氧化物含量和相对良好的机械和热性能，例如，与等离子喷涂涂层相比;然而，实现的钨含量相当低。
Copper and copper-tungsten composite coatings were produced by high-velocity oxy-fuel spraying (HVOF). After initial optimization of the spraying parameters, coatings of various compositions were made and their structure, composition, mechanical, thermal, and electrical properties were characterized. The HVOF technique was able to produce rather dense coatings with minimal oxide content and relatively good mechanical and thermal properties compared to, for example, plasma-sprayed coatings; however, the achieved tungsten content was quite low.
