العنوان: (EN) Cavitation erosion-resistant laser high-entropy alloying powder on stainless steel surface and preparation process thereof
(ZH) 一种不锈钢表面耐空蚀激光高熵合金化粉料及制备工艺
الملخص: front page image
(EN) The invention provides a cavitation erosion-resistant laser high-entropy alloying powder on a stainless steel surface and a preparation process thereof and belongs to the technical field of surface engineering. The component of the high-entropy alloying powder comprises four metal elements, namely Co, Cr, Al and Ni and a non-metal element B; the additive amounts of the metal elements in the powder are equal in molar ratio and the molar number of the non-metal element B is x times that of other component powder, wherein x is greater than or equal to 0 but less than or equal to 1. By adopting a proper laser radiation process parameter, a high-entropy alloy coating which is combined with a stainless steel base material and is uniform and fine in tissue, free of cracks and excellent in cavitation erosion resistance can be prepared by virtue of a surface alloying technology of laser reaction synthesis.
