摘要

本研究提出了一种新的统计模型，用于定量估计不同参数下Ni60A涂层的厚度和硬度，并利用该模型对煤矿机械导轨鞋保护层Ni60A涂层的包覆工艺进行优化。并将优化后的Ni60A涂层的摩擦学性能与相同条件下的基体进行了比较。结果表明，该模型为预估熔覆层显微硬度提供了可行的数学表达式，最小二乘法拟合R2值为98.10%，预测偏差为1.27%。Ni60A涂层的存在有效抑制了微裂纹的扩展能力，从而显著提高了导鞋的耐磨性。

Tribological properties of the optimized Ni-based laser cladding coating in simulated coal mine water environment

This study presents a novel statistical model for quantitatively estimating the thickness and hardness of Ni60A coating under different parameters, which are then utilized to optimize the cladding process for the Ni60A coating used as a protective layer for guide shoes of coal mining machines. Furthermore, the tribological properties of optimized Ni60A coating were evaluated in comparison with those of substrate under identical conditions. The results confirmed that the proposed model offered a viable mathematical expression for estimating the microhardness of cladding layer, with an R² value of 98.10% in least square fitting and a predictive deviation of 1.27%. The presence of Ni60A coating effectively suppresses the propagation ability of microcracks, thereby significantly enhancing the wear resistance of guide shoe.
