Haske mai matsin lamba na matsin lamba na Harafi Yn52s00027p1 ya dace da SK200-6 exvator na Shengang

Don kayan da aka yi amfani da shi a cikin matsanancin matsanancin matsanancin ƙarfi, magani mai zafi da kuma hardening surface yawanci ana amfani dasu don inganta juriya da tsayayya da lalacewa.

1, Vackuum mai zafi

Jiyya mai zafi tana nufin tsarin magani mai zafi wanda aka sanya kayan aikin a wuri. Vuruum mai zafi ba ya haifar da iskar shaye-shaye, kayan abinci da sauran lalata yayin dumama, amma kuma yana da aikin tsarkake farfajiya, digiri da digiri. Hydrogen, nitrogen da oxygen sha da kayan a lokacin smelting za'a iya cire shi a cikin wuri, da kuma ingancin da aikin kayan za a iya inganta. Misali, bayan matattarar zafi mai zafi mai yawan amfani da mai sauƙin da aka saba da W18CR4V, shallafan bawul ɗin allo yana ƙaruwa sosai, kuma a lokaci guda, ana inganta kayan aikin na yau da kullun.

Don inganta aikin ɓangaren ɓangare, ban da canza kayan, ana karbar hanyoyin ci gaba da karfafa magani. Irin wannan yanayin mai zafi (harshen wuta mai tsayi, babban hanyar dumama, condan, mai ɗorewa, mai ɗaukar hoto), Hanyar CLACK), Hanyar CVD), ajiye mai (Hanyar PVD), Hanyar Cikakken Plasma (Hanyar PCVD) plasma spraying, da sauransu.

Ajiyayyen tururi na jiki (hanyar PVD)

A cikin wuri, hanyoyin zahiri kamar ruwa, ana amfani da ion an yi amfani da shi don samar da tsiro na karfe. Wadannan kayan yanka na karfe suna ajiye a farfajiya na aikin don samar da murfin karfe, ko amsa tare da reactor don samar da wani yanki mai shafi. Wannan tsari na jiyya ana kiranta ajiye shi na zahiri, ko pvd na gajere. This method has the advantages of low deposition temperature, 400 ~ 600℃ treatment temperature, small deformation and little influence on the matrix structure and properties of parts. An sanya wani ƙaramin katako a kan allurar bawul ɗin da aka yi da W18cr4V ta hanyar PVD. Tsarin Tin yana da ƙarfi sosai (2500 ~ 3000hv) da babban sanadin juriya, ba shi da tsoratar da hydrochloric acid, kuma zai iya ci gaba da shimfiɗa mai haske. Bayan jiyya na PVD, shafi yana da kyakkyawan daidaito. Zai iya zama ƙasa da goge, kuma saman hadari shine ra0.8μm, wanda zai iya kai wa 0.01μm bayan picking.
