i-molybdenum intonga ejikelezayo ye-High-temperature sintering kunye neshishini lonyango lobushushu

molybdenum umjikelo intonga for High-lobushushu sintering kunye nobushushu ishishini unyango Featured Umfanekiso

Inkcazelo emfutshane:

Iintonga ezingqukuva ze-Molybdenum ngokwenene ziqhele ukusetyenziswa kwimizi-mveliso yobushushu bobushushu obuphezulu kunye nonyango lobushushu ngenxa yeempawu zabo ezibalaseleyo zobushushu obuphezulu. I-Molybdenum's high melting point, i-conductivity ephezulu ye-thermal kunye ne-coefficient ephantsi yokwandiswa kwe-thermal yenza ukuba ifaneleke kakuhle kwezi zicelo.

Luyintoni unyango lobushushu lwemolybdenum?

Ukunyangwa kobushushu be-molybdenum ngokuqhelekileyo kubandakanya iinkqubo eziphucula iimpawu zayo zomatshini ezifana ne-ductility, ukuqina, kunye namandla. Ezona nkqubo zixhaphakileyo zokunyanga ubushushu bemolybdenum ziquka ukuthomalalisa kunye noxinzelelo loxinzelelo:

1. I-Annealing: I-Molybdenum isoloko ihlanjululwa ukunciphisa ubulukhuni bayo kunye nokwandisa i-ductility yayo. Inkqubo yokufunxa idla ngokubandakanya ukufudumeza imolybdenum kwiqondo lobushushu elithile (lidla ngokuba malunga ne-1200-1400°C) kwaye emva koko uyipholise kancinci ukuya kwiqondo lobushushu begumbi. Le nkqubo inceda ukukhulula uxinzelelo lwangaphakathi kunye nokubuyisela kwakhona isakhiwo se-molybdenum, ukuphucula i-ductility kunye nokuqina.

2. Ukunciphisa uxinzelelo: Iindawo ze-Molybdenum eziye zafumana ukusebenza okubandayo okubandayo okanye ukucwangciswa kwemishini kunokunciphisa uxinzelelo lokunciphisa uxinzelelo lwangaphakathi kunye nokuphucula ukuzinza kwe-dimensional. Inkqubo ibandakanya ukufudumeza i-molybdenum kwiqondo elithile lobushushu (ngokuqhelekileyo malunga ne-800-1100 ° C) kwaye uyibambe kwelo qondo lobushushu ixesha elithile ngaphambi kokuyipholisa kancinane. Ukunciphisa uxinzelelo kunceda ukunciphisa ukugqwetheka kunye nokunciphisa umngcipheko wokuqhekeka kwezinto ze-molybdenum.

Kuyafaneleka ukuba uqaphele ukuba inkqubo ethile yokushisa ukushisa kwe-molybdenum inokwahluka ngokuxhomekeke kukwakheka kwe-alloy, isicelo esijoliswe kuyo kunye nezinto eziphathekayo ezifunwayo. Ngoko ke, kuyacetyiswa ukuba udibane nengcali yezinto eziphathekayo okanye ubhekiselele kwizikhokelo ezithile zonyango lwe-molybdenum ukuze uqinisekise unyango olufanelekileyo kwisicelo esinikiweyo.

Yintoni i-sintering ye-molybdenum?

I-sintering ye-molybdenum ibandakanya inkqubo yokudibanisa i-molybdenum powder kunye nokufudumeza kwiqondo lokushisa elingaphantsi kwendawo yokunyibilika kwayo, okubangela ukuba umgubo ngamnye udibanise. Le nkqubo ibangela ukubunjwa kwesakhiwo esiqinileyo se-molybdenum esinamandla aphuculweyo kunye nokuxinana.

Inkqubo ye-sintering idla ngokubandakanya la manyathelo alandelayo:

1. Ukucofa umgubo: Sebenzisa i-mold okanye i-die ukucinezela umgubo we-molybdenum kwimilo oyifunayo. Inkqubo yokudibanisa inceda ukwenza isakhiwo esihambelanayo sibe ngumgubo.

2. Ukufudumeza: I-molybdenum powder edibeneyo ifudunyezwa kwi-atmosphere elawulwayo kwiqondo lokushisa elingaphantsi kwendawo yokunyibilika ye-molybdenum. Eli qondo lobushushu lidla ngokuba phezulu ngokwaneleyo ukwenzela ukuba amasuntswana omgubo adibane kunye ngokusasazwa, enze isakhiwo esiqinileyo.

3. Uxinaniso: Ngethuba lenkqubo ye-sintering, isakhiwo se-molybdenum sixinanisa njengamaqhekeza ngamanye adibanisa. Oku kubangela ukwanda koxinano kunye nokomelela kwamalungu e-sintered molybdenum.

I-Sintering isoloko isetyenziselwa ukuvelisa amacandelo e-molybdenum anemilo enzima kunye neemfuneko eziphezulu zoxinaniso, ezifana nezinto zokufudumeza, iinqununu zesithando somlilo, izikhephe ezitshisayo, njl.
