Materialegenskaper<\/h2>\n

H\u00f6g h\u00e5rdhet och slitstyrka<\/h3>\n

Kiselkarbidkeramik har extremt h\u00f6g h\u00e5rdhet, vilket ger utm\u00e4rkt motst\u00e5ndskraft mot n\u00f6tning och mekaniskt slitage under l\u00e5ngvarig drift.<\/p>\n

Motst\u00e5ndskraft mot korrosion<\/h3>\n

SiC-keramik fungerar bra i sura, alkaliska och kemiskt aggressiva milj\u00f6er, vilket g\u00f6r den l\u00e4mplig f\u00f6r kemiska och industriella system.<\/p>\n

Stabilitet vid h\u00f6ga temperaturer<\/h3>\n

Materialet bibeh\u00e5ller stabila mekaniska prestanda vid f\u00f6rh\u00f6jda temperaturer och termiska cykler.<\/p>\n

L\u00e5g densitet och l\u00e5g friktion<\/h3>\n

J\u00e4mf\u00f6rt med st\u00e5lkulor \u00e4r SiC-keramiska kulor l\u00e4ttare i vikt och bidrar till att minska rotationstr\u00f6gheten och friktionen under drift.<\/p>\n

Termisk konduktivitet<\/h3>\n

Kiselkarbid ger relativt h\u00f6g v\u00e4rmeledningsf\u00f6rm\u00e5ga j\u00e4mf\u00f6rt med m\u00e5nga andra tekniska keramer, vilket hj\u00e4lper till att avleda v\u00e4rme i h\u00f6ghastighetsapplikationer.<\/p>\n

\n

Tillverkningsprocess<\/h2>\n

Beredning av pulver<\/h3>\n

Kiselkarbidpulver med h\u00f6g renhet bearbetas f\u00f6r att s\u00e4kerst\u00e4lla materialkonsistens och strukturell stabilitet.<\/p>\n

Formning och sintring<\/h3>\n

De keramiska kulorna formas och sintras under kontrollerade h\u00f6gtemperaturf\u00f6rh\u00e5llanden f\u00f6r att uppn\u00e5 h\u00f6g densitet och mekanisk styrka.<\/p>\n

Precisionsslipning och polering<\/h3>\n

Varje kula genomg\u00e5r precisionsslipning och polering f\u00f6r att s\u00e4kerst\u00e4lla rundhet, ytj\u00e4mnhet och m\u00e5ttnoggrannhet.<\/p>\n

Kvalitetsinspektion<\/h3>\n
