Atụmatụ na ojiji nke Cemented Carbide

Atụmatụ nke tungsten carbide

Tungsten carbide nwere ike isi ike ma na-eyi nguzogide. Mbelata ngwa ngwa nke carbide ngwaọrụ bụ 4 ruo 7 ugboro dị elu karịa nke ígwè dị elu na 5 ruo 80 ugboro ndụ ọrụ dị elu. Ngwaahịa Carbide nwere ike belata ihe siri ike nke ihe dịka 50HRC. Isiokwu ndị a ga-ewebata ụfọdụ ihe ọmụma dị mkpa banyere carbide cimented.

Njirimara ihe nke tungsten carbide

Carbide cimented na-abụkarị ntụ ntụ nke carbides (WC, TiC) nke ọla na-eme ka ike sie ike dị elu. Ihe ndị bụ isi bụ ngwaahịa metallurgical ntụ ntụ etinyere n'ime ọkụ na-ekpo ọkụ ma ọ bụ ọkụ mbelata hydrogen nwere cobalt (Co), nickel (Ni), na molybdenum (Mo) dị ka ihe nkedo.

Ihe mejupụtara matriks nke carbide cemented mejupụtara akụkụ abụọ: otu akụkụ bụ akụkụ siri ike, akụkụ nke ọzọ bụ metal bonding.

Oge siri ike bụ carbide, dị ka tungsten carbide, titanium carbide na tantalum carbide. Isi ike ya dị oke elu. Ebe mgbaze ya dị n'elu 2000 Celsius, na ụfọdụ gafere 4000 Celsius. Ịdị adị nke usoro ịhịa aka n'ahụ na-ekpebi oke isi ike na iyi nguzogide nke carbide.

Tungsten carbide WC chọrọ nha nha maka carbide cemented jiri ụdị ọka WC dị iche iche dabere na ngwa dị iche iche.

Isiokwu a na-ewebata ụzọ atọ nke cemented carbide:

1. Tungsten carbide maka ime ka carbide ịkpụ ngwaọrụ

A na-eji ngwá ọrụ ịkpụ carbide eme ihe n'ọtụtụ ebe maka ịkpụ ígwè na ígwè. Alloys eji arụ ọrụ mara mma dị ka eriri agụba ụkwụ na mma V-CUT na-eji ultra-fine, sub-fine, na ezigbo ọka WC. Alloys na-arụ ọrụ siri ike na-eji WC ọkara-ọka. Alloys ọnwụ ike ndọda na alloys ịcha ọrụ dị arọ na-eji ọkara na nnukwu WC granular dị ka akụrụngwa.

2. Carbide cimented maka ime ihe eji eme ihe ngwuputa carbide

Nkume ahụ nwere ike siri ike na nnukwu mmetụta dị elu. A nakweere WC siri ike, yana mmetụta nkume dị ntakịrị nwere obere ibu. A na-eji WC nwere ọkara dị ka akụrụngwa.

3. Alloy siri ike maka ime akụkụ ndị na-eguzogide carbide

Mgbe a na-ekwusi ike nguzogide iyi ya, nguzogide mkpakọ, na imecha elu ya, WC nwere nha dị iche iche ka a na-eji dị ka akụrụngwa, a na-eji akụrụngwa WC ọkara na nke siri ike mee ihe dị ka isi ihe.

4. metal siri ike maka ime tungsten carbide anwụ

Carbide nwụrụ nwere ọtụtụ iri ugboro ndụ ọrụ ogologo oge karịa nchara. Akpụkpọ anụ carbide nwere ike siri ike, ike dị elu, nguzogide corrosion, nguzogide okpomọkụ, yana obere ọnụọgụ mgbasawanye, n'ozuzu ya bụ tungsten cobalt.

Ọ bụrụ na ị nwere mmasị na ngwaahịa tungsten carbide ma chọọ ozi na nkọwa ndị ọzọ, ị nwere ike ịkpọtụrụ anyị site na ekwentị ma ọ bụ mail n'aka ekpe, ma ọ bụ zipu ozi US na ala ibe.
