Knives Ruitai Kitchen: Isi mmalite gị maka mma kichin emebere si China
E nwere ụdị ụzọ mkpuchi ihe abụọ a na-ahụkarị: kemịkalụ vapor deposition (cvd) na ntinye ikuku anụ ahụ (pvd) ugbu a. N'ime afọ ndị na-adịbeghị anya, ụfọdụ usoro mkpuchi ọhụrụ apụtala, nke nwere atụmanya ngwa dị mma.
CVD
CVD usoro, nke bụ nke atomic deposition, bụ usoro nke akpụ siri ike deposition oyi akwa n'elu kpo oku matriks site na iji vepo, hydrogen na ndị ọzọ chemical mmiri nke metal halide na elu okpomọkụ nke 950 ~ 1050 ℃. Usoro a na-agụnye usoro atọ: vaporization nke ihe onwunwe, ibuga na gburugburu matriks na nhazi nke ihe mkpuchi na matriks.
N'ime ụdị ụdị cvd niile, vacuum ion bombardment na magnetron ion reaction spray ka kacha eji. A na-eji teknụzụ cvd eme ihe maka mkpuchi elu nke ihe eji egbutu carbide cemented, nke dabara adaba maka ịgbagharị ọsọ dị elu na ọkara imecha nke ọkara na ịcha arọ.
E jiri ya tụnyere ụzọ mkpuchi ndị ọzọ, usoro cvd ọ bụghị nanị na ọ nwere uru nke ngwá ọrụ dị mfe, usoro tozuru okè, kamakwa ọ nwere uru ndị a:
E nwere ọtụtụ ụdị sedimenti, nke a pụrụ iji ọla, alloys, carbide, nitrides, borides, oxides, carbon nitrides, oxygen nitrides, hydro-carbon nitrides, wdg. N'ihe dị elu na ịdị n'otu, enwere ike nweta mkpuchi multilayer na anụ ahụ dị iche iche, na mkpuchi mkpuchi bụ otu. Ọnụ ego nkwụnye ego dị elu ma dị mfe ịchịkwa. Ihe mkpuchi ahụ nwere ịdị ọcha dị elu ma dị mma na oke ọka. Adhesion siri ike nwere ike nweta mkpuchi siri ike. Ọnụ ego usoro dị ala, kwesịrị ekwesị maka mmepụta oke.
PVD
Usoro PVD bụ iwepụ ihe sitere na isi mmalite site n'ụdị anụ ahụ dị ka evaporation ma ọ bụ sputtering, wee tinye ions ndị a na-ekpo ọkụ na mkpụrụ ma ọ bụ akụkụ elu iji mepụta oyi akwa ihe nkiri site na oghere ma ọ bụ oghere oghere. Mmeghachi omume uzuoku nke atom igwe kpochapuru ma ọ bụ sputtered na-eduga na ntinye nke ogige a chọrọ n'elu ngwá ọrụ. pvd mkpuchi nwere ike kpuchie ya na titanium nitride, titanium carbon nitride, aluminum titanium nitrogen ogige, yana dị iche iche refractory ọla nke carbides na nitrides.
A na-eji teknụzụ PVD eme ihe na ọgwụgwọ elu nke ngwaọrụ carbide cemented na ngwa ngwa ngwa ngwa dị elu. A na-eji ya eme ihe n'ọtụtụ ebe na ọgwụgwọ mkpuchi nke cemented carbide bit, onye na-egwe ọka, reamer, mgbata, ngwá ọrụ pụrụ iche, ngwá ọrụ ịgbado ọkụ na ihe ndị ọzọ.
MT-CVD
The tcn mkpuchi na ok fibrous crystalline morphology nwere ike nweta site ọkara okpomọkụ kemịkalụ vepor ntinye (MT-CVD) na 700 ~ 900 ℃. The mkpuchi ọkpụrụkpụ nwere ike iru 8 ~ 10μm, na ike ịbụ a2o3, tin n'elu oyi akwa site cvd technology.
MT-CVD mkpuchi agụba adabara elu na-agba, elu okpomọkụ, ibu ibu, akọrọ ọnwụ ọnọdụ, ndụ ya bụ ihe dị ka okpukpu abụọ dị elu dị ka nke nkịtị mkpuchi agụba. cvd isi ihe ndọghachi azụ nke usoro ahụ bụ na ọnọdụ okpomọkụ dị elu dị elu, na annealing na deformation ga-eme mgbe a na-ekpuchi ngwá ọrụ ígwè dị elu. Ya mere, a ga-emenyụrịrị ngwá ọrụ echekwara.
