Research On The Improvement Of Wear Resistance For Plough-share Edge Surface

In practice, wearing makes a large amount of lost in industry production as one of the main form of expiration. Therefore, how to improve the wear-resistance and increase the service life of the components is very meaningful, and it also decreases the cost and improve the production efficiency. It has become a keystone to fabricate the anti-wear coatings on the surface of the work pieces in present.Part agricultural machinery wear is to grind granule wear mainly. Components such as ploughshare in tillage machine , breast , rake movie , rotary tillage bit, has brought about grave wear there by in the process of school assignment directly to get in touch with soil , the sandstone. The all-round plough point and most breast carry out mill granule friction with soil all in soil when ploughing cultivated land, the person wears away therefore very quickly. That plough point wears the gravest location away is that point gets along most in lower part ploughshare edge and front part. Studying whose cause is main is to improve whose abrasion resistance coming assuming the surface treatment. But, in abroad, the ploughshare edge has done the surface treatment equally have got certain achievement. At present, the ploughshare selling, produces a manufacturer selecting material many , respective differing , the manufacturing engineering be unable completely improves and perfects on home market, the ploughshare causing the domestic ploughshare and entering port is compared with each other , there is is very big difference between abrasion resistance and life time.Be aimed at this one problem during the past the past few years, We have selected and used oxygen acetylene nickel base alloy powder melts from melting apply, the Fe-05I type welding rod electric arc melts apply, the Fe-05 powder piece carbon arc melts apply, the CO2 gas poisons pair of protection melting apply , be unlike this four kinds material , diversity to melt applying method being in progress studying. To the location wearing comparatively grave ploughshare edge face away, melt applying good function alloy able to endure material tier. And the edge selling ploughshare in the day after tomorrow at reduced prices has carried out a hardness on the four kinds , microscopic structure has been in progress to study, By that the hardness testing and the metallographic organize analysis,The function able to endure has improved 3-5 , life time has improved ploughshare edge face to times be the above. Reach by testing that the conclusion studying is comparatively not bad, CO2 gas medicine protects the tier of solder wire better than going a step further other three kinds, to whose main technological parameter intersection angle able to endure melting applying out pair , solder wire reaches out the length , welding current , electric arc voltage and gas rate of flow having carried out an optimization.
