Lub hauv paus ntsiab lus ntawm Metallurgical Powder Sintering

Cov hmoov metallurgy txoj kev yog ua kom cov ntaub ntawv raw ntawm cov hlau ua hmoov, tom qab ntawd sib tov cov hmoov no hauv qhov tsim nyog, thiab tom qab ntawd nias thiab ua kom ruaj khov rau hauv ib qho zoo. Cov hmoov blocks no tau muab tso rau hauv qhov chaw txo qis, xws li hydrogen, rhuab, thiab sintered los ua ib qho alloy. Qhov no yog txoj kev metallurgical uas txawv kiag li los ntawm txoj kev casting yav dhau los.

Sintering raws li tau hais los saum no tuaj yeem txhais tau yooj yim raws li kev txhawb nqa ntawm agglomeration ntawm cov nplej hlau los ntawm kev txiav txim siab thiab kub. Peb siv ib tug npaum li cas ntawm lub siab rau cov hmoov nrog cov alloying muaj pes tsawg leeg rau compact nws. Nyob rau hauv qhov kub thiab txias, cov hmoov nyob rau hauv kev sib cuag nrog ib leeg thiab maj mam sau cov voids los ua ib tug high-density alloy. Cov cua kub ntawm lub sij hawm no yog qhov kub ntawm melting point nyob rau hauv lub alloy Cheebtsam. Yog li ntawd, lub alloy ingot yog sintered ntawm ib tug kub hauv qab no lub melting point ntawm tag nrho cov hmoov muaj pes tsawg leeg. Txoj kev no zoo ib yam li kev sib txuas ntawm ob txheej txheem ntawm melting thiab casting, thiab nws cov khoom yog ze rau cov cam khwb cia alloys. Tab sis los ntawm ib tug metallographic taw tes ntawm view, nws yuav tsum yog ib ceg ntawm alloy castings.

Cemented carbide yog tsim los ntawm cov hmoov metallurgy txoj kev no. Feem ntau, cov hmoov xws li tungsten, carbon, cobalt, titanium, thiab cerium yog siv rau kev sib xyaw ua ke, ces nias thiab sintered los ua cov alloys. Yog li ntawd, cov khoom ntawm cov txheej txheem metallurgical no tseem hu ua cemented carbide lossis cemented carbide. Nyob rau hauv xyoo tas los no, hmoov metallurgy txoj kev tau tsim sai heev. Carbide, roj-muaj alloys, hluav taws xob tiv tauj, hlau-bonded pob zeb diamond sib tsoo log, thiab cov khoom tshwj xeeb zoo nkauj hlau yog tsim los siv cov hmoov hlau metallurgy.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa mus rau US MAIL hauv qab ntawm nplooj ntawv.
