Tungsten Carbide VS HSS (2)

Umahluko wezithako zezinto eziphathekayo

I-tungsten carbide

I-carbide ene-cemented inecandelo eliphambili le-metal high hardness refractory carbide kunye ne-WC powder, i-cobalt (CO) okanye i-nickel (Ni), kunye ne-molybdenum (MO) njenge-binder. Yimveliso ye-metallurgical powder efakwe kwi-vacuum furnace okanye isithando sokunciphisa i-hydrogen.

HSS

Insimbi enesantya esiphezulu yintsimbi eyinkimbinkimbi, enomxholo wekhabhoni ngokubanzi phakathi kwe-0.70% kunye ne-1.65%, i-18.91% umxholo we-Tungsten, i-5.47% ye-rubber ye-Chloroprene, i-0.11% ye-Manganese.

Umahluko wenkqubo yemveliso

I-tungsten carbide

Ukwenziwa kwe-carbide enesamente kuxuba i-tungsten carbide kunye ne-cobalt kwinqanaba elithile, licinezela kwiimo ezahlukeneyo, kwaye emva koko i-semi-sintering. Le nkqubo ye-sintering idla ngokuqhutyelwa kwi-vacuum furnace. Ifakwe kwi-oven yokucoca ukugqiba ukutshisa, kwaye ngeli xesha, ubushushu bumalunga ne-1300 ° C kunye ne-1,500 ° C. I-sintered tungsten carbide forming iye yacinezela umgubo kwindawo engenanto kwaye emva koko ifudunyezwe kwinqanaba elithile kwisithando somlilo. Kufuneka igcine iqondo lobushushu ixesha elithile ize iphole, ngaloo ndlela ifumana izinto ezifunwayo ze-carbide.

HSS

Inkqubo yokunyanga ukushisa kwe-HSS inzima ngakumbi kune-carbide ene-cemented, ekufuneka icinywe kwaye ihlanjululwe. Ukucima, ngenxa yokungahambi kakuhle kwe-thermal, ngokuqhelekileyo kwahlulahlulwe ngamanqanaba amabini. Hlaziya kuqala kwi-800 ~ 850 °C, ukuze ungabangeli uxinzelelo olukhulu lwe-thermal, ngoko ngokukhawuleza ubushushu kubushushu bokucima i-1190 ° C ukuya kwi-1290 °C eyahlula xa amabakala ahlukeneyo ekusetyenzisweni okuyinyani. Emva koko zipholisa ngokupholisa i-oyile, ukupholisa umoya, okanye ukupholisa ngegesi.

Ukusetyenziswa kwezixhobo ze-tungsten carbide kunye nezixhobo ze-HSS

I-tungsten carbide

I-Tungsten carbide inokusetyenziswa njengezixhobo zokomba amatye, izixhobo zokomba, izixhobo zokomba, izixhobo zokulinganisa, iintsimbi zokunxiba i-carbide, ii-cylinder liners, ii-cylinder liners, ii-bearings ezichanekileyo, ii-nozzles, iimolds ze-hardware ezifana nomzobo wocingo ziyafa, i-bolt iyafa, i-nut iyafa, kunye ne-fastener eyahlukeneyo. iyafa, enentsebenzo egqwesileyo, ngokuthe ngcembe ithatha indawo yentsimbi yangaphambili.

HSS

I-HSS inokusebenza kakuhle kwenkqubo kunye nokudityaniswa okuhle kwamandla kunye nokuqina, ngoko ke isetyenziselwa ukwenza izixhobo zokusika isinyithi ezinemiphetho ecekethekileyo entsonkothileyo kunye nokumelana nempembelelo entle, iibheringi zobushushu obuphezulu kunye nokungunda okubandayo.

Isishwankathelo

Isixhobo se-tungsten carbide siya kuba lolona khetho lungcono kuninzi oluqhelekileyo lwesinyithi. I-carbide ene-cemented inomsebenzi ongcono kune-HSS, enesantya esiphezulu sokusika, ubomi benkonzo ende, kunye nokumelana nokugqwesa okugqwesileyo. Isinyithi esinesantya esiphezulu sifanelekile ngakumbi kwizixhobo ezinemilo enzima.
