Kedu ihe siri ike

Hardfacing bụ itinye akwa mkpuchi nke ihe siri ike, ihe na-agaghị eyi n'elu akwa eyi ma ọ bụ nke ọhụrụ a ga-eyi.site ịgbado ọkụ, thermal spraying, ma ọ bụ yiri usoro. A na-ejikarị spraying thermal, spray-fuse na welding usoro iji tinye akwa ihu siri ike. Ihe ndị a na-etinyekarị na-agụnye alloys dabere na cobalt (dịka tungsten carbide) alloys dabeere na nickel,chromium carbidealloys, wdg. A na-esochi hardfacing mgbe ụfọdụ site na stampụ ọkụ iji mechaa akụkụ ahụ ma ọ bụ tinye agba ma ọ bụ ozi nkuzi na akụkụ ahụ. Enwere ike iji foils ma ọ bụ ihe nkiri mee ihe maka ọdịdị ọla ma ọ bụ nchebe ọzọ

A na-ahọrọ spraying thermal maka ngwa na-achọ ntakịrị mgbagha nke akụrụngwa na njikwa usoro dị mma. Ihe ndị siri ike na-echekwa site na ịgbasa ọkụ gụnyere cermets dị ka WC-Co na ceramik dabere na alumina. A na-etinye mkpuchi ndị a na ọkpụrụkpụ nke ihe dịka 0.3mm.

A na-ebu ụzọ tinye ihe mkpuchi fesa-fuse nke a na-akpọkwa dị ka mkpuchi mkpuchi nke na-agbapụta onwe ya, nke a na-ebu ụzọ tinye ya n'elu ihe mejupụtara ya site na iji usoro ịgbasa ọkụ wee mechaa jikọta ya site na iji ọwa oxyacetylene ma ọ bụ eriri induction RF. Ihe mkpuchi a jikọtara ọnụ na-eme ka mmiri dị n'elu ala iji mepụta mkpuchi nke ejiri metallurgic jikọtara ya na mkpụrụ na enweghị porosity. Enwere ụdị alloy dị iche iche nke ejiri usoro ịgbasa-fuse, nke kachasị mkpa dabere na sistemụ alloy Ni-Cr-B-Si-C. Dabere na ihe mejupụtara ha na-agbaze na nso 980 ruo 1200 Celsius. 

A na-eji ihu siri ike weld na-edobe akwa akwa (1 ruo 10mm) akwa akwa nke ihe na-agaghị eyi nke nwere ike njikọ dị elu. Enwere ike iji usoro ịgbado ọkụ dị iche iche, gụnyere gas metal-inert (MIG), tungsten inertgas (TIG), Plasma bufere arc (PTA), arc nke submerged (SAW), na ntuziaka metal arc (MMA). Enwere ike itinye ihe mkpuchi sara mbara nke ukwuu. Ha gụnyere alloys dabere na cobalt (tungsten carbide wdg.), Martensitic na elu-ọsọ nchara, nickel alloys na WC-Co cemented carbides. Mgbe ntinye site na nke ọ bụla n'ime usoro ịgbado ọkụ dị n'elu, ọ na-adịkarị mkpa imecha elu ihe mejupụtara.

Enwere ike idobe Hardfacing site na ụzọ ịgbado ọkụ dị iche iche:
