Ukusetyenziswa ngokubanzi kwekhabhide enesamente

Ngaba uyazi ukusebenza kwe-carbide enesamente?

Ubunzima obuphezulu (86-93HRA, ngokulingana ne-69-81HRC);

Ukuqina okuhle kwe-thermal (kunokufikelela kwi-900-1000 ℃, gcina i-60HRC);

Ukumelana nokunxiba kakuhle.

Isantya sokusika izixhobo ze-carbide si-4 ukuya kumaxesha angama-7 aphezulu kuneyentsimbi ephezulu, kwaye ubomi besixhobo bu-5 ukuya kumaxesha angama-80 ubude. Ukwenziwa kobunjwa kunye nezixhobo zokulinganisa, ubomi buyi-20 ukuya kumaxesha angama-150 ubude kunobo bensimbi ye-alloy tool. Inokusika izinto eziqinileyo malunga ne-50HRC.

Nangona kunjalo, i-carbide enesamente i-brittle kakhulu kwaye ayinakunqunyulwa. Kunzima ukuyenza ibe sisixhobo esidityanisiweyo esintsonkothileyo. Ke ngoko, ihlala iyenziwa ibe ngamagqabi eemilo ezahlukeneyo kwaye ifakwe kumzimba wesixhobo okanye umzimba wokubumba ngokufakwa kwe-welding, i-bonding, i-clamping ngoomatshini, njl.

I-alloy imathiriyeli eyenziwe ngeekhompawundi eziqinileyo zesinyithi esichasayo kunye neentsimbi zokubopha ngesinyithi somgubo. I-carbide enesamente inothotho lweempawu ezigqwesileyo ezinjengokuqina okuphezulu, ukuxhathisa ukunxiba, ukomelela okulungileyo kunye nokuqina, ukumelana nobushushu, kunye nokumelana nokugqwala. Ngokukodwa, ubunzima bayo obuphezulu kunye nokumelana nokunxiba kuhlala kungatshintshi nakwiqondo lobushushu le-500 ° C, kwaye kusenobunzima obuphezulu kwi-1000 ° C.

I-carbide ene-cemented isetyenziswa ngokubanzi njengezixhobo zesixhobo, ezifana nezixhobo zokujika, ii-milling cutters, iiplani, iidrili, izixhobo ezikruqulayo, njl.njl., ukusika intsimbi, iintsimbi ezingezizo ezoni, iiplastiki, imicu yemichiza, igraphite, iglasi, ilitye kunye nentsimbi eqhelekileyo. Ingasetyenziselwa ukusika intsimbi ekwazi ukumelana nobushushu, insimbi engenasici, intsimbi ephezulu yemanganese, intsimbi yesixhobo kunye nezinye izinto ekunzima ukuzisebenzisa. Ngoku isantya sokusika izixhobo ezintsha ze-carbide ngamakhulu amaxesha e-carbon steel. Inoluhlu lweempawu ezibalaseleyo ezifana nobunzima obuphezulu, ukuxhathisa ukunxiba, ukomelela okulungileyo kunye nokuqina, ukuxhathisa ukushisa, ukuxhathisa ukubola, njl., ngokukodwa ubunzima bayo obuphezulu kunye nokumelana nokunxiba, okuhlala kungaguqukiyo kwiqondo lokushisa lama-500 ° C, kwaye kusenobunzima obuphezulu kwi-1000 ° C.

I-carbide ene-cemented isetyenziswa ngokubanzi njengezixhobo zokujika, izixhobo zokusila, iiplani, iidrili, izixhobo ezikruqulayo, njl., ukugawula intsimbi, isinyithi esingenawo, iiplastiki, imicu yekhemikhali, igraphite, iglasi, ilitye kunye nentsimbi eqhelekileyo, kwaye ingasetyenziselwa ukugawula intsimbi enganyangekiyo ubushushu, insimbi engenasici, intsimbi ephezulu ye-manganese enzima, isixhobo sentsimbi kunye nesinyithi. Ngoku isantya sokusika izixhobo ezintsha ze-carbide ngamakhulu amaxesha e-carbon steel.
