Mumakore achangopfuura, silicon carbide coating yave ichinyanya kutariswa uye kushandiswa, kunyanya kana tembiricha yakakwira, kumanikidzwa kwakanyanya, kusakara, ngura uye mamwe mamiriro ekushanda akaomarara, pakati payo silicone coating isingakwanise kusangana nezvinodiwa kusvika pamwero wakati, silicon carbide coating yave sarudzo yakakurumbira yezvimwe zvingasarudzwa. Silicon carbide coating, inozivikanwawo secarbon silicide, ipurasitiki inodzivirira kusakara inoumbwa nekabhoni nesilicon. Saka, iyi coating inobatsira here? Ngatitaurei nezvemhedziso dzedu.
Chekutanga, chimwe chezvakanakira zve silicon carbide coating ndechekuti ine resistance yakanaka yekupfekwa. Munzvimbo dzakadai semotokari dzechitima dzinomhanya zvakanyanya, kugadzira michina, kugadzira chakuvhuvhu, aerospace uye kufamba, kushandiswa kwe silicon carbide coating yakaoma, resistance yekupfekwa kunovandudzwa zvikuru, saka zvinogona kuvandudza hupenyu hwebasa uye kugara kwenguva refu kwezvinhu. Kune michina nemidziyo inoda kushanda kwenguva yakareba, silicified carbon coating material inogona kutochengetedza mari yakawanda, nekuti inogona kuderedza kupera kwezvikamu, kuwedzera hupenyu hwebasa remidziyo, uye kuderedza zvakanyanya mari yekugadzirisa.
Chechipiri, silicon carbide coating inewo mamwe maitiro ekudzivirira ngura uye oxidation. Munzvimbo dzakasiyana-siyana dzeacid, alkali nedzimwe nzira dzekurapa ngura uye nzvimbo dzekupisa kwakanyanya, silicon carbide coating haizoratidzike seyakaora uye oxidation, kuitira kuti ive nechokwadi chekuti zvinhu zvakaputirwa zvinoshandiswa uye mhando yacho inoshandiswa.
Uyezve, kunamira kwesilicon carbide coating kwakasimba, kunogona kusungirirwa zvakasimba kune zvinhu zvakaputirwa, kuitira kuti ive nechokwadi chekugadzikana uye kuvimbika kwehupenyu hwebasa. Mundima yekugadzira nekugadzira maindasitiri, se tekinoroji yepamusoro yekuputira, inogona zvakare kubereka mifananidzo yakaoma kwazvo uye nzvimbo dzakanyatsojeka, kuitira kuti isangane nezvinodiwa zvehuwandu hwakawanda, kunyatsojeka kwechimiro chakakwirira, uye zvinodiwa zvemhando yepamusoro zvezvigadzirwa zvakakosha.
Ehe, pane zvipingamupinyi pakugadzirwa kwesilicon carbide. Chekutanga, mutengo wekugadzirira silicified carbon coating wakakwira, uye kushandiswa kwayo kunoda tekinoroji yepamusoro, michina yakawanda uye nzira yakawanda yekugadzirisa inotora nguva, saka mutengo wayo wakakwira. Chechipiri, nekuti silicified carbon coating inoumbwa pamusoro pechinhu ichi nenzira yemakemikari, ukobvu hwayo uye kufanana kwayo nefirimu zvinokanganiswa nyore nyore nezvinhu zvakawanda zvakaita semaitiro ekugadzira, zvinhu zvemuenzaniso uye saizi, zvekuti haigone kuchinjika kune mamwe mamiriro chaiwo.
Muchidimbu, silicon carbide coating ndeimwe ye coating inoshanda zvakanyanya uye ine mabasa akawanda. Ine zvakanakira zvekudzivirira kubva pakusakara, kuramba ngura, kuomarara kwakanyanya, kuramba oxidation, kunamira kwakasimba nezvimwe zvinhu, asi panguva imwe chete, kune mitengo yakakwira yekugadzira, ukobvu hwefirimu husina kuenzana nezvimwe zvikanganiso. Zvisinei, kana tichienzanisa ne coating yechinyakare, silicon carbide coating yafambira mberi zvikuru uye chiyero chekushandiswa kwayo chakawedzerwa zvishoma nezvishoma. Nekuvandudzwa kuri kuramba kuchiitwa uye kuvandudzwa kwetekinoroji, zvinotendwa kuti silicon carbide coating ichashandiswa munzvimbo dzakawanda uye ichagadzira mabhenefiti akawanda uye kukosha kwevanhu.
