Mukuchengetedza kwemazuva ano, nekuvandudzika kuri kuramba kuchiita simba rezvombo, zvinodiwa zvekushandisa zvombo zvisingapindi mabara zviri kuramba zvichiwedzera kuoma.Silicon carbide, chinhu chinoratidzika sechisina kujairika asi chine simba guru, chiri kubuda zvishoma nezvishoma sechinhu chitsva chinodiwa muindasitiri yekudzivirira mabara. Nhasi, tichaburitsa pachena chifukidziro chisinganzwisisike chekudzivirira mabara esilicon carbide.
1, Kuburitsa musimboti wekudzivirira mabara
Chinhu chikuru chekudzivirira nhumbi dzesimbi chiri pakushandisa simba rema "projectile", zvichidzikisa kumhanya kusvika dzarasikirwa nenjodzi yadzo. Zvinhu zvesimbi zvechinyakare zvinoshandisa purasitiki kuti zvitore simba, nepo zvinhu zveceramic zvichizadzisa chinangwa ichi kuburikidza nekuita micro crushing process yakasiyana. Tichitora silicon carbide bulletproof ceramics semuenzaniso, kana projectile yarova, projectile inotanga yagomara ipapo ipapo pamusoro pe "impact surface", uye ceramic surface inopwanywa kuti iite nzvimbo yakaoma yakapwanyika. Maitiro aya akafanana nekupa projectile "nyundo" uye pakutanga ichitora simba; Zvadaro, projectile yakapwanyika yakaramba ichienda mberi, ichibvisa nzvimbo yakapwanyika uye ichigadzira chidimbu chinoenderera mberi chezvidimbu zveceramic; Pakupedzisira, ceramic fractures pasi pekumanikidzwa, uye backplate inotanga kuora. Simba rasara rinotorwa zvachose ne "deformation" ye backplate material.
2, Sei silicon carbide ichigona kudzivirira mabara?
Silicon carbide imhando yesimbi inoumbwa ne covalent bonds, uye Si-C bonds dzayo dzinogona kuchengetedza simba rakawanda pakupisa kwakanyanya. Chimiro ichi chakasiyana chinopa silicon carbide ceramics zvinhu zvakawanda zvakanaka. Ine kuomarara kwakanyanya, yechipiri kune dhaimani, cubic boron nitride, uye boron carbide pakati pezvinhu zvakajairika. Yakafanana nehondo yakapfeka nhumbi dzakasimba, inokwanisa kudzivirira kurwiswa nepfuti; Panguva imwe chete, ine density yakaderera uye huremu hwakareruka kana yagadzirwa kuita michina inodzivirira mabara. Ingave yehondo yega yega kana yakagadzirirwa mota nendege, haizove mutoro wekuwedzera, asi inogona kuvandudza kufamba kwemayuniti ehondo. Pamusoro pezvo, silicon carbide inewo kugadzikana kwakanaka kwekupisa uye kuramba ngura kwemakemikari, uye inogona kutamba basa rekudzivirira mabara munzvimbo dzakasiyana-siyana dzakaoma.
3, Mabhenefiti akasiyana ekuita sintered silicon carbide muzvikamu zvakagadzirirwa
Mukugadzirira silicon carbide ceramics, reaction sintered silicon carbide (RBSiC) inonyanya kuoneka, inonyanya kukodzera kugadzirwa kwezvikamu zvakagadzirwa, nekuda kwezvikonzero zvinotevera:
1. Kuwanda kwemafuta uye simba rayo: Kana tembiricha yakakwira, kabhoni yakasununguka inopindirana nesilicon yemvura kuti igadzire makristaro matsva esilicon carbide. Panguva imwe chete, silicon yakasununguka inopinda uye inozadza maburi, ichiwedzera zvakanyanya kuwanda kwezvinhu, ichisvika padanho redzidziso. Izvi hazvingogumiri pakusimbisa uye kukotama kwechinhu chacho, asiwo zvinochipa simba rakanaka rekupfeka, iro rinogona kutsungirira kumanikidzwa kwakanyanya uye mamiriro ekusimba kwakanyanya, zvichisangana nezvinodiwa zvezvikamu zvakagadzirirwa kuti zvisimbe uye zvigare kwenguva refu.
2. Magadzirirwo emukati mechinhu anogona kudzorwa: Maitiro ekuita kuti zvinhu zvisashande zvakanaka anogona kudzora kukura kwezviyo, zvichigadzira magadzirirwo madiki uye akafanana. Magadzirirwo aya akanaka anowedzerawo hunhu hwezvinhu, zvichiita kuti zvirambe zvakagadzikana uye zvisanyanya kutsemuka kana kukuvara kana zvasangana nematambudziko akasiyana-siyana akaomarara, zvichipa vimbiso yakasimba yekuvimbika kwezvikamu zvakagadzirwa.
3. Kururama kwepamusoro: Munguva yekusimbaradza, shanduko dzehukuru hwe reaction sintered silicon carbide hadzina kunyanya kukosha, izvo zvakakosha kune zvikamu zvakagadzirwa. Ingave chivharo chimwe chete chemauto chinodzivirira mabara chine maumbirwo akaomarara kana chikamu chekudzivirira chemotokari chakakosha chine zvinodiwa zvakakura, zvinogona kugadzirwa nemazvo kuti zvive nechokwadi chekuti zvinoenderana nemidziyo.
4. Kugadzikana kwakanaka kwemakemikari: Silicon carbide ine reaction sintered haina maburi akavhurika, zvichiita kuti zviomere okisijeni nezvinhu zvinoparadza kupinda mukati mechinhu chacho, nokudaro zvine simba guru rekudzivirira oxidation uye ngura. Izvi zvinoreva kuti zvigadzirwa zvesilicon carbide zvakagadzirwa zvinogona kuramba zvichishanda zvakanaka, kuwedzera hupenyu hwebasa, uye kuderedza mari yekugadzirisa munzvimbo dzakaoma dzechisikigo kana dzemakemikari kwenguva yakareba.
4, Silicon carbide application proof field
Nekushanda kwayo kwakanaka, zvinhu zvesilicon carbide zvisingapindi mabara zvakashandiswa zvakanyanya muminda yakawanda:
1. Midziyo yega yega: jira rekudzivirira mabara resilicon carbide, ngowani isingapindi mabara, nezvimwewo, zvinopa varwi dziviriro yakareruka uye yakakwirira, zvichivabvumira kurwa zviri nyore munhandare yehondo uku vaine dziviriro yakachengeteka yakavimbika.
2. Mota dzakakosha: dzakadai semotokari dzehondo, mota dzinotakura mari, mota dzinorwisa hugandanga uye dzinodzora mhirizhonga, nezvimwewo, dzakashongedzerwa nesimbi yesimbi yesilicon carbide ceramic muzvikamu zvakakosha, iyo inogona kudzivirira kurwiswa kwezvombo zvakasiyana-siyana uye kuchengetedza kuchengetedzeka kwevashandi nezvinhu zvakakosha mukati memotokari.
3. Mudenga: Zvinhu zvisingapindi mabara zvesilicon carbide zvinoshandiswa pamaherikoputa ane zvombo nedzimwe ndege kuderedza huremu hwadzo, kuvandudza mashandiro ekubhururuka, uye kuwedzera kugona kwadzo kudzivirira kubva kumoto wemuvengi, zvichiita kuti ndege dzive dzakachengeteka.
Nekufambira mberi kwetekinoroji, zvinhu zvisingapindi mabara zvesilicon carbide zvicharamba zvichigadzirwa uye zvichivandudzwa, zvichivaka tambo yakasimba yekudzivirira kuchengetedza. Kana uchida zvikamu zvakagadzirwa zvesimbi dzesilicon carbide, ndapota inzwa wakasununguka kutibata.
