"It is the organization performance of the alloy that this text has studied C-Cr-Mo-V which resists the wearing and tearing with better ability , have tested and made different welding rods of many kinds of alloy matching by rubing with the hands and making by hand, on piling and welding to and trying the board the welding rod by exchanging the electric arc welder , then carried on Rockwell hardness in piling and welding samples and is tested , organizes observing and compositions to measure . Pass the hardness of each kind of sample correctly, the organization and analysis of compositions, must produce the alloying element to piling the influence law which weld the wear-resisting performance of alloy and obtaining the best alloy composition matching finally.
It is all low carbon or horse's body and body of high carbon basically that C-Cr-Mo-V piles and welds one layer of metal, and there is netted or cubic carbide that organizes and presents the carbide particle that the disperse form is distributed in the body in the base , wearability of improving the base the body surface. It is wrong to pile and weld the location where one layer of metal has slipped and moved and presented the high density while taking in the course of assaulting, the location of these high density makes the crystal slip and move and is obstructed, cause materials to be strengthened by mistake; A large number of location tangles is it is it in brilliant circle , cause location sport and crystal obstruction moved to slip increase greatly by mistake finally to pitch to nail by mistake at the same time, this is the main reason that the macroscopical hardness increases after material deformation.

The research capacity of the wear-resistant alloys is better C-Cr-Mo-V organizational performance, the use of manual testing of the entire system to produce a variety of alloys limited means different welding rod, will be used to exchange electric arc butt welding rod Duihan to ban pop, and then a specimen of Duihan got hardness testing, component testing and observation organizations. By the hardness of each specimen, organization and content analysis, the final conclusion alloy elements Duihan alloy wear-resistance and the impact of limited access to the best alloy components. C-Cr-Mo-V Duihan layer metal are basically low or high-carbon martensite and austenite, and the presence of network or matrix organizations and a massive carbide dispersible warrants distribution carbide particles and increased matrix surface resistance to abrasion. Zuihan layer metal process in the impact zone, a high-density slip the wrong place, these high-density places wrong to crystal slip blocked, causing material reinforced; At the same time a large number of spaces in the wrong knot and nails Norte crystal community, and ultimately lead to the wrong place and crystal slip resistance movement greatly increased material deformation which is the main cause of increased macro hardness.
