In the present work, two different hardfacings, namely SZ (Super-Zed alloy; C3.83Cr33.37) and ZK (Zedalloy-K; C0.65Cr4.5Mo8.18) were deposited on EN-47 ploughshare steel by manual metal arc welding process to enhance the abrasive wear resistance. In addition, the influence of heat-treatment of steel by two different methods, i.e., carburizing (C) and through-hardening (Q&T), on the abrasive wear behaviour has also been investigated. Abrasive wear studies were conducted on bare, hardfaced, and heat-treated steel in a laboratory by using a three-body dry sand rubber wheel test rig as per the ASTM G-65 standard. The bare steel suffered a high wear rate, which may be attributed to its soft ferritic-pearlitic microstructure. The abrasive wear rate of tested specimens was found to be 1.7651 × 10 −3 g m −1 , 0.7439 × 10 −3 g m −1 , 0.961 × 10 −3 g m −1 , 0.992 × 10 −3 g m −1 and 1.21 × 10 −3 g m<...

耕作应用的EN-47硬面和热处理钢的摩擦学性能

在目前的工作中，通过手工金属电弧焊在EN-47犁ough钢上沉积了两种不同的堆焊层，即SZ（超Zed合金； C3.83Cr33.37）和ZK（Zedalloy-K； C0.65Cr4.5Mo8.18）。焊接过程中增强了耐磨性。另外，还研究了通过两种不同的方法（即渗碳（C）和直通淬火（Q＆T））对钢进行热处理对磨料磨损行为的影响。使用ASTM G-65标准的三体干砂橡胶轮试验装置，在实验室中对裸露，硬面和热处理的钢进行磨料磨损研究。裸钢具有较高的磨损率，这可能归因于其软的铁素体-珠光体显微组织。发现测试样品的磨料磨损率为1.7651  ×  10 -3 gm -1，0.7439 ×  10 -3 gm -1，0.961  ×  10 -3 gm -1，0.992  ×  10 -3 gm -1和1.21 ×  10 -3 gm  <...
