Ndezvipi Zvimiro Zvinofanira Kuve Nemafuta Anopfapfaidza Powders?

Mukuwedzera pakusangana nezvinodiwa zvekushanda kwejasi, iyothermal spray powderinofanirawo kusangana nezvinodiwa zvekupfapfaidza maitiro: inogona kutakurwa mujet murazvo unoyerera zvakafanana, zvakanaka uye zvakatsiga kuti ive yakagadzikana uye yakafanana thermal spray coating.Naizvozvo, hunhu hwehupfu hwehupfu hwakadai sechimiro, saizi yechidimbu uye kugovera saizi yechikamu, kuwanda kwehuwandu, fluidity uye mhando yepamusoro, zvakakosha zvikamu zvekushanda kwehupfu hwekupfapfaidza hupfu.

(1) Morphology yehupfu zvidimbu

Mazhinji emafuta ekupfapfaidza alloy poda zvinhu zvinogadzirwa nenzira yeatomization, uye iyo poda particle morphology inonyanya kureva chimiro chejometri uye hunhu hwepamusoro hwehupfu.Iyo geometry inogona kuongororwa nekuyera chiyero cheiyo axis pfupi kune axis refu (nhamba yenhamba) ye elliptical spherical particles.Iyo yakakwirira iyo spheroidization degree, zviri nani iyo solid-state fluidity yehupfu.Sezvo dhigirii yehupfu spheroidization haingobatanidzi neatomization poda yekugaya nzira uye atomization milling process parameters, asiwo kune kemikari yehupfu pachayo.Naizvozvo, iyo spheroidization dhigirii yemhando dzakasiyana dzehupfu zvakare yakasiyana, asi inofanirwa kuve nechokwadi kuti nzira yekupfapfaidza inogona kuve yakatsetseka uye kunyange yekudyisa hupfu.

Kune dzimwe nguva maburi ehukuru hwakasiyana mukati meiyo thermal spray metal poda zvimedu zvakagadzirirwa neatomization, mamwe ayo anopinda kumusoro, uye mamwe anovharika mukati mezvimedu.Kana iyo yekupfapfaidza isina kunaka, ichava nemhedzisiro yakananga pamhando yekupfekedza.Kuti uone maburi akadaro, optical metallographic microscope inowanzoshandiswa.Mamiriro epamusoro anoreva ruvara rwepamusoro, kutsvedza, nezvimwe.

(2) Chikamu chehupfu

Kusarudzwa kwehupfu hwehupfu uye huwandu hwayo hunonyanya kutsanangurwa nekupfapfaidza nzira yekupfapfaidza uye kupfapfaidza maitiro ekugadzirisa paramita.Kunyangwe kana hupfu hwehupfu hwehukuru hwakafanana, chikamu chechikamu chegiredhi saizi yekuumbwa hachina kufanana.Semuenzaniso: kunyangwe saizi yehupfu iri muchikamu che125μm ~ 50μm (-120mesh~+320mesh), chikamu chehupfu chezvikamu zvitatu zvakasiyana-siyana zvemagiredhi e100μm ~ 125μm, 80μm ~ 100μm, 50μm ~ 80μm hazvina kufanana. .Iyo poda particle size renji uye chidimbu chayo saizi giredhi kuumbwa zvine mhedzisiro yakananga pamhando yekuputira, hupfu huzhinji density uye fluidity.

(3) Bulk Density yeUpfu

Powder bulk density inoreva kuwanda kwehupfu payuniti imwe chete kana ichinge yazara zvisina tsarukano.Sezvo kuwanda kwehupfu hwehupfu hunoenderana nedhigirii re spheroidization yehupfu, ukuru uye huwandu hwemakomba mukati mehupfu, uye kuumbwa kwehupfu hwehupfu, zvinokanganisawo kunaka kwekupfapfaidza.

(4) Kuyerera kwehupfu

Kuyerera kwehupfu ndiyo nguva inodiwa kuti hupfu hwakatarwa huyerere zvakasununguka kuburikidza nefunnel yakajairika ine aperture yakatarwa.Inowanzoonekwa nenguva (s) inodiwa kuti 50g poda iende kuburikidza nefunnel yakajairika ine dhayamita ye2.5mm.Iine kumwe kurudziro pakupfapfaidza maitiro uye kupfapfaidza kunyatsoshanda.
