Hunhu hunokosha hwenano-silicon nitride ultrafine silicon nitride poda yakagadzirwa neyakasiyana nzira, kuchena kwepamusoro, diki diki saizi, kugovera, yakakura pamusoro penzvimbo, basa repamusoro, kushomeka kwehuwandu, UV kuratidza mwero we95% uye kutorwa kweiyo infrared absorption rate pamusoro pe97%. , mudziyo kuita porcelain yakaderera tembiricha, yakanaka dimensional kugadzikana, yakakwirira mechani simba, kuramba makemikari ekuora, yakakwirira tembiricha simba, uye yega-lubricating mhedzisiro mumubatanidzwa mukuumbwa kwechikamu chakanaka chakapararira, nekudaro kuvandudza zvakanyanya kuita kwese kwemubatanidzwa. .Zvigadzirwa zvayo zvine self-lubricating properties, zvinogona kushandiswa kumafuta.Iyo yakakwira kuomarara kwesilicon nitride, iyo coefficient yeinotsvedza friction maitiro inogona kuiswa kune simbi pamusoro peceramic kupfeka-inodzivirira composite coatings, yakaiswa kune iyo machira inogona kutamba inopfeka-inodzivirira uye inonyungudika maitiro, yakakwira-kuchena silicon nitride inogona kushandiswa. mune quartz crucible kuburitsa mumiririri ane.
Applications
Kugadzirwa kwemidziyo yezvimiro: senge bhora uye roller yemabhengi anotenderedza anoshandiswa mune metallurgical, makemikari, michina, ndege, aerospace uye simba maindasitiri, plain bearings, sleeve, valve, uye kupfeka, yakakwirira tembiricha kuramba, corrosion kuramba zvinodiwa magadzirirwo emidziyo.rocket nozzles, missile ine nozzle;
Simbi uye zvimwe zvigadzirwa zvepamusoro kurapwa: senge molds, maturusi ekucheka, turbine blades, turbine rotor uye humburumbira madziro coating alloy;
3 zvinhu zvakaumbwa: simbi, ceramics, uye graphite-based composites, rabha, mapurasitiki, coatings, adhesives uye mamwe mapolymer-based composite;
4 pfeka wega-kuzora nanoparticle mafirimu enharembozha, mota uye kumwe kudzivirira kwepamusoro, kupfeka-inodzivirira coating, electrophoresis pendi yekuwedzera, tamba yakakwira abrasion maitiro.
