Refractory tungsten simbi uye tungsten alloys ane zvakanakira kugadzikana kwekushisa kwepamusoro, kuramba kwakanyanya kutama maerekitironi uye yakakwira maerekitironi emission coefficient. Yakakwirira-kuchena tungsten uye tungsten alloy zvinangwa zvinonyanya kushandiswa kugadzira gedhi electrode, yekubatanidza wiring, diffusion barriers layers ye semiconductor integrated circuits. Ivo vane zvakanyanya zvakanyanya zvinodikanwa pakuchena, kusachena chinhu chemukati, density, saizi yezviyo uye yunifomu yezviyo chimiro. Ngatitarisei zvinhu zvinokurudzira kugadzirira kwepamusoro-kuchena tungsten chinangwaby Rich Special Material Co.,Ltd.
I. Mhedzisiro yeSintering Temperature
Iyo yekuumba maitiro e tungsten target embryo inowanzoitwa nekutonhora isostatic pressure. Tungsten tsanga ichakura panguva yekupisa. Kukura kwezviyo zve tungsten kuchazadza mukaha pakati pemiganho yekristaro, nekudaro kuwedzera kuwanda kwechinangwa che tungsten. Nekuwedzera kwenguva dze sintering, kuwedzera kwehuwandu hwe tungsten chinangwa chinodzikira zvishoma nezvishoma. Chikonzero chikuru ndechekuti mhando ye tungsten inotariswa zvinhu haina kuchinja zvakanyanya mushure mekuita akati wandei sintering. Nekuda kwekuti mavhodhi akawanda ari mumuganho wekristaro akazadzwa netungsten makristasi, huwandu hwese hwekuchinja saizi ye tungsten tarisiro idiki kwazvo mushure mega yega sintering process, izvo zvinokonzeresa nzvimbo shoma yekuti tungsten target density iwedzere. Sezvo sintering ichienderera mberi, hombe tungsten zviyo zvinozadzwa mumavoids, zvichikonzera denser chinangwa nehukuru hudiki.
2. Mhedzisiro yehidya kuchengetedza Nguva
Panguva imwechete yekupisa tembiricha, iyo compactness ye tungsten inonangwa zvinhu inovandudzwa nekuwedzera kwenguva yekupisa. Nekuwedzera kwekupisa nguva, tungsten saizi yezviyo inowedzera, uye nekuwedzera kwekupisa nguva, kukura kwezviyo kunowedzera zvishoma nezvishoma. Izvi zvinoratidza kuti kuwedzera iyo sintering nguva kunogona zvakare kuvandudza mashandiro e tungsten chinangwa.
3. Mhedzisiro yeRolling pane Target Performance
Kuti uvandudze density ye tungsten inotariswa zvinhu uye kuwana iyo yekugadzirisa chimiro che tungsten inotariswa zvinhu, yepakati tembiricha yekutenderedza ye tungsten yakananga zvinhu zvinofanirwa kuitwa pazasi recrystallization tembiricha. Kana tembiricha yekutenderera yechinangwa chisina chinhu ichikwira, iyo fiber chimiro chechinangwa chisina chinhu chinokora, nepo icho chechinangwa chisina chinhu chiri nani. Kana goho rinopisa riri pamusoro pe95%. Kunyangwe mutsauko wefiber chimiro chakakonzerwa neyakasiyana sintering yepakutanga zviyo kana tembiricha yekutenderedza ichabviswa, yakawanda homogeneous fiber chimiro ichaumbwa mukati mechinangwa, saka iyo yakakwira chiyero chekugadzirisa kwekudziya kwekutenderera, zvirinani kuita kwechinangwa.
