摘要

研究了基于自流变 PG-10N-01 合金的复合材料（CM）沉积层的微观结构，该复合材料通过自蔓延高温合成获得，并用机械活化的 CM 对其进行了改性。X 射线相分析表明，在沉积层结构中，镍硼化物 NiB、Ni2B、Ni3B、铬硼化物 CrB、Cr2B、铬碳化物 Cr3C2、Cr7C3 等夹杂物分布在镍基体中。电弧焊接过程中的改性 CM 有助于磨削结构、降低摩擦系数、提高熔敷涂层的显微硬度以及降低各种摩擦条件下的磨损强度。

Structure and Tribotechnical Properties of Deposited Composite Layers Based on PG 10N-01 Alloy Containing AL2O3

The microstructure of deposited layers with a composite material (CM) based on the self-fluxing PG-10N-01 alloy, modified with a mechanoactivated CM obtained using the self-propagating hightemperature synthesis, was studied. The X-ray phase analysis revealed in the deposited layer structure the inclusions of nickel borides NiB , Ni₂B , Ni₃B , chromium borides CrB , Cr₂B , chromium carbides Cr₃C₂ , Cr₇C₃ , distributed in the nickel matrix. The modifying CM during arc welding contributed to the grinding of structure and reduction of the friction coefficient, increase of the microhardness of the deposited coatings, and decrease of the wear intensity in various friction conditions.
