Preparation method of cladding alloy layer on matching surface of concave spherical surface and convex spherical surface and support
According to the preparation method of the cladding alloy layer on the matching surface of the concave spherical surface and the convex spherical surface and the support, high-speed laser cladding is carried out on the matching surface of the concave spherical surface and the convex spherical surface to form the cladding alloy layer to replace traditional stainless steel spherical surface cladding, and the phenomena that stainless steel and a base material are not tightly attached and disengaged can be avoided. The preparation method of the cladding alloy layer comprises the following steps: performing laser cladding on alloy powder on a matching surface on which the cladding alloy layer needs to be formed through a high-speed laser cladding device so as to form the cladding alloy layer on the matching surface; then, the cladding alloy layer is polished; in the laser cladding process, the shielding gas flow is controlled to be 2-20 L/min, the powder feeding gas flow of the alloy powder is 1-3 L/min, the laser power is controlled to be gradually increased to 90% from 20%, and the powder feeding amount of the alloy powder is gradually increased to 75 g/min from 1.5 g/min; and the cladding height is controlled to be 15-25 mm.
本发明提供一种凹、凸球面配合面上的熔覆合金层的制备方法以及支座，本发明通过在凹、凸球面配合面上进行高速激光熔覆形成熔覆合金层来替代传统的不锈钢球面包覆，可以避免出现不锈钢和基材不密贴、脱空的现象。所述熔覆合金层的制备步骤包括：通过高速激光熔覆装置将合金粉末激光熔覆于需要形成熔覆合金层的配合面上，以在所述配合面上形成所述熔覆合金层；然后对所述熔覆合金层进行抛光；在进行所述激光熔覆过程中，控制保护气流量为2‑20L/min，所述合金粉末的送粉气流量为1‑3L/min，控制激光的功率从20％逐渐增大至90％，合金粉末的送粉量从1.5g/min逐渐增大至75g/min；熔覆高度控制为15‑25mm。
