I-carbide enesamente, njenge "amazinyo oshishino", sisixhobo esiyimfuneko kwizixhobo zanamhlanje. Ukusetyenziswa kwayo kuya kusasazeka ngokubanzi, kwaye ithandwa kakhulu kwiindawo ezininzi ezifana neoli kunye negesi, imigodi yamalahle, ukulawula ulwelo, oomatshini bokwakha, i-aerospace kunye nokunye. Ke, ukusebenzisa izixhobo ezilinganiselweyo ukuphucula ukusebenza kakuhle? Oku kufuna ukuphucula ukusebenza kwe-carbide ene-cemented ukuphucula ubomi benkonzo kunye nokusebenza kakuhle.

1.Ukuphucula umgangatho wemathiriyeli ekrwada.

A.Ukuphucula ukucoceka kwemathiriyeli ekrwada

Kukholelwa ukuba ukulandelela izinto ezifana neNa, Li, B, F, Al, P, K kunye nezinye izinto ezilandelwayo ezinomxholo ongaphantsi kwe-200PPm zineempembelelo ezahlukeneyo ekunciphiseni, i-carbonization kunye ne-sintering ye-cemented carbide ye-N powder, Kwaye impembelelo kwiipropati kunye nesakhiwo se-alloy nayo ifanelekile ukufunda.Ngokomzekelo, ii-alloys ezinamandla amakhulu kunye nokuqina kwempembelelo ephezulu (ezifana ne-alloys yemigodi kunye nezixhobo zokugaya) zineemfuno eziphezulu, ngelixa i-alloys yesixhobo esiqhubekayo sokusika kunye nomthwalo wempembelelo ephantsi kodwa ephezulu. ukuchaneka machining ayifuni eliphezulu izinto ekrwada ubunyulu.

B.Lawula ubungakanani bamasuntswana kunye nokuhanjiswa kwezinto ekrwada

Gwema amaqhekeza angaphezulu kwi-carbide okanye i-cobalt powder izinto eziluhlaza, kwaye uthintele ukubunjwa kweenkozo ze-carbide kunye namachibi e-cobalt xa i-alloy is sintered.

Kwangaxeshanye, ubungakanani bamasuntswana kunye nobungakanani bamasuntswana enziwe ngezinto ekrwada zilawulwa ukuhlangabezana neemfuno zeemveliso ezahlukeneyo. Ngokomzekelo, izixhobo zokusika kufuneka zisebenzise i-tungsten carbide powder kunye ne-Fisher particle size ngaphantsi kwe-2 microns, izixhobo zokunxiba kufuneka zisebenzise i-2-3 microns tungsten carbide powder, kunye nezixhobo zemigodi kufuneka zisebenzise i-tungsten carbide powder enkulu kune-3 microns.

2. Ukuphucula i-microstructure ye-alloy.

I-Ultrafine Grain Alloy

Ubungakanani bengqolowa ye-carbide bungaphantsi kwe-1μm, kwaye ingaba nobunzima obuphezulu kunye nokuqina ngexesha elifanayo.

I-Heterogeneous Structural Alloys

I-Heterogeneous structure alloy luhlobo olukhethekileyo lwe-carbide ene-cemented ene-microstructure engalinganiyo okanye ukubunjwa, okwenziwa ngokuxuba iindidi ezimbini zemixube kunye namacandelo ahlukeneyo okanye ubungakanani bamasuntswana ahlukeneyo. Ihlala inokuqina okuphezulu kwe-alloys ene-coarse-grained alloys kunye nokumelana okuphezulu kwe-alloys enegrained alloys, okanye zombini ukuqina okuphezulu kwe-cobalt alloys ephezulu kunye nokumelana nokunxiba okuphezulu kwe-cobalt alloys ephantsi.

I-Superstructural Alloys

Ngokusebenzisa inkqubo ekhethekileyo yokuvelisa, ulwakhiwo lwe-alloy luqulunqwe nge-anisotropic tungsten carbide enye imimandla ye-crystal flake edityaniswe yi-cobalt-rich metal veins. Le alloy inokumelana nokunxiba okugqwesileyo kunye nokuqina okuphezulu kakhulu xa iphantsi koxinzelelo oluphindaphindiweyo.

Ingxubevange yeGradient

Iialloyi ezinotshintsho lwegradient ekubunjweni zikhokelela kutshintsho lwegradient kubulukhuni kunye nokuqina.

3. Ukuphucula okanye ukhethe isigaba esitsha esinzima kunye nesigaba sokudibanisa.

4. Unyango lokuqina komphezulu.

Sombulula ukuchasana phakathi kokumelana nokunxiba kunye nokuqina, ukuqina kunye namandla e-carbide enesamente.

Ukwaleka:Deposit umaleko we-TiC okanye i-TiN kumphezulu we-alloy eqinile kunye nokuqina okungcono ngeendlela zomzimba okanye zekhemikhali ukunyusa ukuxhathisa ukunxiba kwe-alloy.

Okwangoku, olona phuhliso lukhawulezayo lwe-boronizing, i-nitriding, kunye ne-spark spark deposition yi-carbide enesamente enesamente.

5. Ukongeza izinto okanye iikhompawundi.

6. Ukushisa ukunyangwa kwe-carbide ene-cemented.
