Embodiment Construction

[0010] A new type of wear-resistant surfacing welding electrode, including a welding core and a coating. The welding core is an H08A welding core, and the mass percentage of the coating is: C: 0.5-1.5%, Cr: 7-11% , Si: 0.5-1.5%, Mo: 1-4%, V: 2-4%, Re: 0.5-2%.

[0011] Using Si, Mo, Cr, V as additive elements improves the wear resistance of the metal substrate using the new wear-resistant surfacing electrode, among which Cr can increase the strength and hardness of the coating, while reducing the plasticity and toughness Not much, Mo can refine grains, prevent temper brittleness, increase red hardness, reduce crack tendency, and improve impact damage resistance. V can refine the eutectic structure, improve the distribution of carbides, and at the same time inhibit the occurrence of welding hot cracks. Si can improve the thermal strength of steel and improve thermal fatigue resistance. Re can refine grains and purify grain boundaries. , Eliminate harmful impurities and purify t...

Abstract

The invention relates to a novel hardfacing electrode, and belongs to the field of wear resistant protection. The novel hardfacing electrode comprises a core wire and a coating, wherein the coating comprises the following components in percentage by mass: 0.5 to 1.5 percent of C, 7 to 11 percent of Cr, 0.5 to 1.5 percent of Si, 1 to 4 percent of Mo, 2 to 4 percent of V and 0.5 to 2 percent of Re.The application of the novel hardfacing electrode is that: by a manual arc welding method, a Fe-C-Si-Mo-Cr-V-Re coating with the thickness of 0.5mm is prepared on the surface of a metal substrate. The invention has the characteristics that: the novel hardfacing electrode is convenient to machine, has stable performance and low cost, and the like; and compared with an unprocessed base material, a base material processed by the novel hardfacing electrode has obvious wear resistance and great economic and social benefits, and the service life of the base material can be dramatically improved.

Description

technical field [0001] The invention relates to a novel wear-resistant surfacing electrode, which belongs to the field of wear-resistant protection. Background technique [0002] In the world, the direct loss caused by the wear and tear of materials is more than 30 billion U.S. dollars every year. This loss not only wastes a lot of materials, but also causes a lot of indirect losses. Therefore, in recent years, with the need for energy saving and emission reduction, the green remanufacturing industry has emerged. The core of this industry is an industry based on surface engineering. Since most parts fail on the surface, the surface of the failed parts is prepared. A new layer of coating can not only ensure the needs of the surface, but also make the core and other parts continue to be used, which can save a lot of material costs and processing costs. Therefore, surface engineering is a good example of energy saving and emission reduction. Use Surface surfacing technology is...
