摘要/Abstract

摘要： 采用分子动力学方法模拟计算了低压冷喷涂过程中不同金属元素粉末的最低沉积温度.计算结果表明:Mn粒子在600 K时就可以有效沉积;Fe粒子需要700 K及以上的喷涂温度;Cr粒子则需要1 100 K及以上温度才能有效沉积;而Al和Cu粒子在500~800 K的温度均可以实现有效沉积,并且两种粒子的扁平率最大值超过了0.6.不同金属元素混合粉末在700 K沉积时,由于沉积过程中不同粉末颗粒的相互影响和夯实作用,即使Cr粒子未达到沉积条件,Cr粒也和其他元素颗粒一样沉积在涂层中.

Abstract: The molecular dynamics method was used to simulate the minimum deposition temperature of different metal powders in the process of low pressure cold spraying. The calculation results showed that Mn particles can be effectively deposited at 600 K, Fe particles need a spraying temperature of 700 K and above, and Cr particles need 1 100 K and above to be deposited effectively. Al and Cu particles can be effectively deposited in the temperature range of 500~800 K, and the maximum flattening rate of the two particles exceeds 0.6. When the powders of different metal elements are mixed and deposited at 700 K, due to the interaction and tamping effect of different powder particles during the deposition process, even if the Cr particles do not reach the deposition conditions, the Cr particles are also deposited in the coating like other element particles.
