This welding wire not only has the inherent properties of metal powder-cored wire, such as with better welding quality, without slag, highly efficiency and conveniently adjusting the alloying elements etc., but also has the advantage of low hardness in as-welded (less than HRC45), good machinability, high hardness in as-aged (more than HRC55) and better wear resistance with customary working procedure on making or repairing equipments such as rollers when reasonable designing the alloys content. The author adequately makes use of the high-tempering in the required stress relieving working procedure. During this working procedure, which causes the hardness of overlaying metal increased by the reason of austenite changes into tempered martensite and more chiefly what is the precipitation of a lot of carbide by secondary hardening simultaneously. This wire can solve the hard rolled problems of some solid wires with higher alloys while it can get over the conflict of existing overlaying materials what are always possesed high hardness with poor machinability or low hardness, good machinability with poor wear resistance. Further, it also can overcome the intenerating phenomena between welding beads and make the external hardness of overlaying metal uniform. Be sure it could be found important meaning in the overlaying of wear-resistant equipments, such as the precise roller.
该焊丝除了具有金属粉型药芯焊丝焊接质量好、无渣、高效率和合金成分可方便调节等固有的优点外,合理的设计粉芯中的合金成分,按通常工序制造与修复轧辊等设备,充分利用必需的消除应力工序的高温回火,堆焊层金属在奥氏体转变为回火马氏体的同时更主要是通过二次硬化析出了大量碳化物导致硬度增加,使得该焊丝还具有焊态硬度低(小于HRC45)、机加工性能好和时效态硬度高(大于HRC55)、耐磨性能好等优点,解决了某些高合金实芯焊丝轧制困难的问题,同时克服了现行堆焊材料硬度高、加工性能差或者硬度低、加工性能好、耐磨性差的矛盾,并能克服焊道之间的软化现象,使堆焊表面硬度较为均匀,对耐磨件,譬如精轧辊的堆焊具有重要意义。

It was believed that either alumina reacted with impurities in the iron powder or the surface diffusion caved the alumina particles to stick to the iron powder surfaces. Another approach was to use the air classifier mill to break up the sintered iron cakes into powders. The morphology of such particles was classified into 4 types in this study: irregular, equalaxed, near spherical, and flaky. The morphological differences were affected by the extent of sintering. The higher the extent of sintering, the stronger the inter-particle bonding.
此外,本实验利用空气分级气流粉碎机将还原后的烧结体进行粉碎,实验结果显示粉碎后的粉末形貌可以分为四种,不规则形、等轴形、近球形和片形,形貌上的差异是由於还原时铁粉烧结程度的不同,烧结程度越高,粉末间键结强度越强,因此粉碎过程中会产生高程度的塑性变形,以至於粉末形貌越来越接近球形,最后因粉末表面大量加工硬化产生破裂,形成片状碎屑。
