摘要

本文介绍了热冲击对低合金贝氏体类金属多层熔覆过程中组织形成影响的研究结果。这种金属的结构是在部分再结晶和回火作用的影响下形成的，其特征是包层金属中贝氏体铁素体的形态变化，并以高角度晶界（θ >； 15°）为主。研究发现，为了在熔覆层向基体（碳钢）过渡时形成平滑的硬度梯度，熔覆层必须在能量输入速率至少为18 kJ/cm的条件下进行。对“母材-亚层-耐磨层”组合物进行热循环，显示了将所开发的低碳低合金金属作为冶金工艺工具耐磨覆层的亚层的潜力。

Prospects of application of low-alloyed bainite class metal for sublayer formation during multilayer cladding of metallurgical equipment parts

The article presents the results of studying the influence of thermal impact on structure formation during multilayer cladding of low-alloyed bainite-class metal. The structure of such metal, formed under the influence of partial recrystallization and tempering effects, is characterized by a change in the morphology of bainitic ferrite with a predominance of high-angle grain boundaries (θ > 15 deg.) in the clad metal. It was found that in order to form a smooth hardness gradient while transitioning from the clad to the base metal (carbon steel), it is necessary to perform cladding under conditions that provide a rate of energy input of at least 18 kJ/cm. The conducted thermal cycling of the composition “base metal—sublayer—wear-resistant layer” has shown the potential for using the developed low-carbon low-alloyed metal as a sublayer for wear-resistant cladding of metallurgical process tools.
