低摩擦系数Fe基非晶态合金涂层的激光熔覆制备方法
摘要：
本发明公开了一种低摩擦系数Fe基非晶态合金涂层的激光熔覆制备方法，属于激光熔覆技术领域。所述方法步骤如下：(1)在钢铁零件表面制备Ni-P非晶过渡层；(2)在Ni-P非晶过渡层表面预置Fe基非晶态合金粉末；(3)利用激光辐照使Fe基非晶态合金粉末熔化并涂覆在零件表面形成涂层；(4)检查涂层厚度，若涂层厚度达到目标厚度，步骤(3)所得涂层即为所述的低摩擦系数Fe基非晶态合金涂层；若涂层厚度未达到目标厚度，重复步骤(2)和(3)，直至涂层厚度达到目标厚度，即得到所述的低摩擦系数Fe基非晶态合金涂层。本发明制备得到的Fe基非晶态合金涂层具有非常低的摩擦系数，且该方法工艺简单。
摘要（英）：

The invention discloses a laser cladding preparation method for a low-friction-coefficient Fe-base amorphous alloy coating and belongs to the technical field of laser cladding. The method includes the steps that step1, an Ni-P amorphous transition layer is prepared on the surface of a steel part; step2, Fe-base amorphous alloy powder is pre-arranged on the surface of the Ni-P amorphous transition layer; step3, laser irradiation is used for melting the Fe-base amorphous alloy powder with which the surface of the part is coated to form a coating; step4, the thickness of the coating is checked, if the thickness of the coating reaches a target thickness, the coating obtained through the step3 is the low-friction-coefficient Fe-base amorphous alloy coating, and if the thickness of the coating does not reach the target thickness, the step2 and the step3 are repeated until the thickness of the coating reaches the target thickness, so that the low-friction-coefficient Fe-base amorphous alloy coating is obtained. The Fe-base amorphous alloy coating prepared through the method has a low friction coefficient, and the method is simple in technology.
