冷喷涂技术是近几年发展起来的新型喷涂工艺,低压冷喷涂是基于原冷喷涂技术上的一种改进,它与高压冷喷涂一样是冷喷涂技术的最常见的两个分支。通过对低压冷喷涂与原冷喷涂技术的工艺差别的比较,从技术原理、涂层的制备和性能分析的角度,分析这种新型的低压喷涂技术的应用前景。 Cold spraying technology is a new type of spraying technology developed in recent years. Low pressure cold spraying is an improvement on the original cold spraying technology, which is the most common two branches of cold spraying technology like high pressure cold spraying. Based on the comparison of technical differences between low-pressure cold-spraying and cold-spraying, the application prospect of this new low-pressure spraying technology is analyzed from the aspects of technical principle, preparation of coating and performance analysis.
