Chii chinonzi resistance evaporation source coating?

Resistance evaporation source coating ndiyo yakakosha vacuum evaporation coating nzira."Evaporation" inoreva nzira yakatetepa yekugadzira firimu umo iyo yekubikira mukamuri yevacuum inodziya uye nekubuda, kuitira kuti maatomu echinhu kana mamorekuru anonyungudika uye apukunyuke kubva pamusoro, achigadzira chiitiko chekuyerera kwemhute, chiitiko pamusoro pemvura. substrate kana substrate, uye pakupedzisira yakanyungudutswa kuita firimu rakasimba.

Iyo inonzi resistance evaporation source coating method ndeye kushandisa tantalum, molybdenum, tungsten uye mamwe masimbi anonyungudika kuti aite chimiro chakakodzera chekubuda kwemvura sosi, iyo inotakurwa nezvinhu kuti zvifukidzwe, rega mhepo ipinde mukati, kupisa kwakananga uye kupisa. evaporate zvinhu zvabuda evaporated, kana kuisa zvinhu kuti zvibudiswe mualumina, beryllium oxide uye mamwe macrucibles ekudziya zvisina kunanga uye evaporation.Iyi ndiyo nzira yekudzivirira kupisa evaporation.

Thevacuum evaporation coating machinekupisa uye evaporated nekupikisa heater ine zvakanakira chimiro chakareruka, mutengo wakaderera uye kushandiswa kwakavimbika.Inogona kushandiswa pakuputira evaporation yemidziyo ine yakaderera kunyungudika, kunyanya kugadzirwa kwemazhinji ine yakaderera zvinodiwa zvemhando yekupfeka.Kusvika pari zvino, kuchine huwandu hukuru hwekuputira maitiro ekudzivirira kupisa uye evaporation inoshandiswa mukugadzira magirazi ane aluminized.

Izvo zvisingabatsiri zvekupikisa evaporation source evaporation coating nzira ndeyokuti tembiricha yepamusoro inogona kusvikwa nekupisa ishoma, uye hupenyu hwebasa hwehita zvakare hupfupi.Mumakore achangopfuura, kuitira kuvandudza hupenyu hweanopokana evaporation sosi, fekitori yemidziyo yakatora iyo conductive ceramic material yakagadzirwa ne boron nitride nehupenyu hurefu sehupo hwekubuda.Sekureva kwemushumo wepatent yeJapan, inogona kushandisa zvinhu zvinoumbwa ne20% ~ 30% boron nitride uye zvinhu zvinoramba zvinogona kusanganiswa nazvo kugadzira iyo inoputika sosi (crucible), uye kupfekedza pamusoro payo nejira re zirconium ine 62% ~ 82%, uye mamwe ese ari zirconium-silicon alloy zvinhu.
