Description

technical field [0001] The present application relates to the field of metal material composite chips, in particular, to a high-throughput preparation method for thick film composite material chips based on multi-source plasma spraying and laser post-treatment. Background technique [0002] Material innovation is not only the core element of developing various disruptive technologies, but also the cornerstone of modern high-end manufacturing and the carrier of technological development. However, the speed of traditional material research and development based on "trial and error" can no longer meet the needs of the current society. Therefore, there is an urgent need to develop rapid and effective means of research and development of new materials. The high-throughput preparation of thin-film composite chips based on magnetron sputtering has been relatively mature, but the preparation of thick films with higher melting points has not yet appeared, so the preparation technolog...
