During cold spraying of ceramic and metal mixtures, there is an interaction between the ceramic and metal particles during the spray process; as a result, under certain conditions, a non-monotonic dependence of deposition efficiency on the content of ceramic particles in the initial powder mixture is observed. In the present work, a numerical Monte Carlo model is put forward for the first time to simulate such behavior of deposition efficiency. The calculation results were compared with the available experimental data. It is shown that, with a proper choice of the values of involved model parameters, one can invent an adequate quantitative description of both the behavior of the deposition efficiency of the mixture and the behavior of the ceramic content of the coating. Additionally, the effects of particle size, particle size distribution, and deposition efficiency of pure metal powder are discussed.

金属和陶瓷粉末混合物冷喷涂过程的蒙特卡罗模拟

在陶瓷和金属混合物的冷喷涂过程中,陶瓷和金属颗粒在喷涂过程中会发生相互作用。结果,在某些条件下,观察到沉积效率对初始粉末混合物中陶瓷颗粒含量的非单调依赖性。在本工作中,首次提出了数值蒙特卡洛模型来模拟这种沉积效率的行为。计算结果与可用的实验数据进行了比较。结果表明,与所涉及的模型参数的值的适当选择,可以发明混合物的沉积效率两者的行为和涂层的陶瓷含量的行为的适当定量描述。此外,粒径,粒径分布,
