I-Cobalt kwiNkqubo ye-Cemented Carbide

Kule mihla, ngenxa yokuba i-carbide ene-cemented inobunzima obuphezulu, ukuxhathisa ukunxiba, kunye ne-elastic modulus, izixhobo ze-carbide ezenziwe ngesamente zidlala indima ebalulekileyo xa ukhangela izixhobo zale mihla, izinto zokuxhathisa, izixhobo zokushisa eziphezulu, kunye nezixhobo zokuxhathisa ukubola. Ekubeni i-Co ine-wettability efanelekileyo kunye ne-adhesive kwi-WC kunye ne-TiC, isetyenziswa ngokubanzi njenge-adhesion agent kwishishini njengesixhobo sokusika. Ukusebenzisa i-Co njenge-adhesion agent yenza ukuba i-carbide enesamente ibe yinzuzo yamandla aphezulu, ubunzima obuphezulu, kunye nokumelana nokunxiba okuphezulu.

Nangona kunjalo, ngenxa yexabiso eliphezulu lentsimbi ye-cobalt kunye nokunqongophala kwezixhobo, abantu baye bajonga izinto ezithatha indawo ye-cobalt metal. Izinto ezisetyenziswayo ngoku zi-nickel kunye ne-iron. Ngelishwa, ukusebenzisa umgubo wentsimbi njenge-adhesion agent idla ngokuba namandla aphantsi oomatshini. Ukusebenzisa i-nickel ecocekileyo njenge-agent adhesion agent ye-carbide ebonakalayo kunye ne-mechanical properties ye-carbide enesamente ayilungile njengabo basebenzisa i-cobalt njenge-adhesion agent. Ulawulo lwenkqubo lukwanzima ukuba usebenzisa i-nickel ecocekileyo njenge-adhesion agent.

Indima ye-cobalt kwi-carbide ene-cemented njenge-adhesion adhesion metal. I-Cobalt inokuchaphazela ukuqina kwe-carbide enesamente ngokusebenzisa isakhono sayo sokuguqulwa kweplastiki kwiqondo lokushisa. I-carbide ene-cemented yenziwa yinkqubo yokutshisa. I-cobalt kunye ne-nickel iba yi-adhesion ye-adhesion yendalo yonke ye-carbide enesamente. I-Cobalt inempembelelo ebalulekileyo kwimveliso ye-carbide enesamente, kwaye malunga ne-90% ye-carbides ene-cemented isebenzisa i-cobalt njenge-adhesion agent.

I-carbide ene-cemented yenziwe nge-carbides eqinile kunye neentsimbi zokubambelela ezithambileyo. I-Carbide inika amandla okumelana nomthwalo kunye nokunxiba ukuxhathisa kwi-alloy, kunye ne-adhesion agent inikezela ukukwazi ukuguqula iplastiki kwiqondo lokushisa. Ukuqina kwempembelelo ye-carbide. Ukuqinisekisa ukuba iimveliso ze-sintered zikwimeko efanelekileyo, ii-adhesion agents zidlala indima ebalulekileyo ekumanziseni i-carbide enesamente.

Uluhlu lwe-tungsten-cobalt carbides lusetyenziselwa ukusika iingcebiso zesixhobo kunye nezixhobo zemigodi ezifuna ukusebenza kwiindawo ezinobunzima obuphezulu. Ezinye izixhobo zotyando ezihlala ixesha elide kunye neemagnethi ezisisigxina nazo zenziwe ngee-cobalt alloys.

I-ductility kunye nokuqina kweemveliso ze-carbide ze-cemented zinganikwa yi-adhesion agent. Ngelo xesha, i-adhesion agent ibonelela ngekhono le-carbide ene-cemented cemented high-melting inokwenziwa kwiindawo kwiqondo lokushisa elingaphantsi kwendawo yokunyibilika.

I-agent egqwesileyo yokubambelela kufuneka ikwazi ukumanzisa ngokupheleleyo indawo ephezulu yokunyibilika ye-carbide enesamente. I-iron, i-cobalt, kunye ne-nickel zonke zinokuhlangabezana neemfuno ze-adhesion efanelekileyo yokubambelela.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
