Ụdị mkpuchi bụ isi nke igwe ihe igwe ọgwụgwụ

A na-akpọkwa igwe ihe igwe ngwụcha carbide dị ka igwe ihe eji eji ciment emechara carbide. Ike nke ngwá ọrụ n'onwe ya na-adịkarị n'etiti ogo HRA88-96. Ma na mkpuchi n'elu, ihe dị iche na-abịa. Ụzọ dị ọnụ ala iji melite arụmọrụ nke igwe njedebe bụ ịgbakwunye mkpuchi kwesịrị ekwesị. Ọ nwere ike ịgbatị ndụ ngwá ọrụ na arụmọrụ.

Kedu ihe mkpuchi bụ isi nke igwe ihe igwe n'ahịa?

1.TiN - Titanium Nitride - isi n'ozuzu-ebumnobi eyi mkpuchi na-eguzogide ọgwụ

TiN bụ ihe mkpuchi siri ike na-eyi na abrasion na-emekarị. Ọ na-ebelata esemokwu ahụ, na-abawanye nkwụsi ike kemịkalụ na okpomọkụ ma na-ebelata ịrapagidesi ike nke ihe na-emekarị n'oge a na-eji ígwè dị nro. TiN kwesịrị ekwesị maka mkpuchi nke ngwá ọrụ mere nke cemented carbides- akuakuzinwo ibe n'ibe, egwe ọka cutters, ọnwụ ngwá ọrụ inserts, taps, reamers, punch knives, ọnwụ ngwaọrụ, shiee na mgbanwe ngwaọrụ, matrices, ụdị, wdg Ebe ọ bụ biocompatible, ọ nwere ike. a ga-eji na ngwa ahụike (ịwa ahụ na eze) na ngwaọrụ etinyere. N'ihi ụda agba ọla edo ya, TiN achọpụtala ọtụtụ ojiji dị ka mkpuchi ịchọ mma. A na-ewepụ ihe mkpuchi TiN a na-eji ngwa ngwa na nchara ngwá ọrụ. Ndozi ngwaọrụ nwere ike ibelata ọnụ ahịa nke ukwuu karịsịa mgbe ị na-eji ngwá ọrụ dị oke ọnụ.

2.TiCN - Titanium Carbo-Nitride - eyi mkpuchi na-eguzogide ọgwụ megide nrapado corrosion

TiCN bụ mkpuchi ebumnuche niile mara mma. TiCN siri ike yana mmetụta na-eguzogide karịa TiN. Enwere ike iji ya kpuchie ngwá ọrụ ịkpụ, ịkụ ọkpọ na akpụ ngwá ọrụ, ihe ndị na-emepụta injection na ihe ndị ọzọ na-eyi. Ebe ọ bụ na ọ dakọtara, enwere ike iji ya na ngwa ahụike yana ngwaọrụ etinyere ya. Enwere ike ịbawanye ọsọ machining yana enwere ike ịkwalite oge ndụ ngwaọrụ site na 8x dabere na ngwa, coolant na ọnọdụ igwe ndị ọzọ. A na-atụ aro mkpuchi TiCN ka e jiri ya mee ihe maka ịkpụ mma nke ọma n'ihi nkwụsi ike ya dị ala. A na-ewepụ ihe mkpuchi TiCN eji eme ihe ngwa ngwa ma weghachite ngwá ọrụ ahụ. Ndozigharị ngwaọrụ ndị dị oke ọnụ nwere ike ibelata ọnụ ahịa nke ukwuu.

3. Ihe mkpuchi aluminium-titanium-nitride (AlTiN)

Ọ bụ ngwakọta kemịkalụ nke aluminom, titanium na nitrogen. Ọkpụrụkpụ mkpuchi ahụ dị n'etiti 1-4 micrometer (μm).

Akụkụ pụrụ iche nke mkpuchi AlTiN bụ oke nguzogide okpomọkụ na oxidation. Nke a bụ akụkụ n'ihi nano hardness nke 38 Gigapascal (GPa). N'ihi ya, ọ na-esote na sistemu mkpuchi ahụ n'agbanyeghị ọsọ igbupu dị elu yana okpomọkụ dị elu ka na-akwụsi ike. Tụnyere ngwaọrụ enweghị mkpuchi, mkpuchi AlTiN, dabere na ngwa a, na-abawanye ndụ ọrụ ihe ruru okpukpu iri na anọ.

Ihe mkpuchi nke nwere aluminium dị oke mma dabara nke ọma maka ngwa nkenke, nke na-egbutu ihe siri ike dịka ọmụmaatụ. ígwè (N/mm²)

Okpomọkụ ngwa ngwa kacha bụ 900º Celcius (ihe dị ka 1,650° Fahrenheit) ma atụnyere mkpuchi TiN iguzogide okpomọkụ dị 300º Celcius.

Ịjụ oyi abụghị iwu. N'ozuzu, Otú ọ dị, jụrụ oyi na-abawanye ndụ ọrụ nke ngwá ọrụ.

Dịka ekwuru na mkpuchi TiAlN n'ozuzu, ekwesịrị ị mara na ma mkpuchi ma igwe akụrụngwa ga-adabara ngwa n'ime ihe siri ike. Ọ bụ ya mere anyị ji jiri AlTiN kpuchie ihe egwu egwu pụrụ iche nke tungsten-carbide mere.

4.TiAlN - Titanium Aluminom Nitride - na-eyi mkpuchi na-eguzogide ọgwụ maka ịcha ọsọ dị elu

TiAlN bụ mkpuchi nke nwere ike siri ike na oke okpomọkụ na nguzogide oxidation. Ntinye nke aluminom butere mmụba nke nguzogide okpomọkụ nke mkpuchi PVD a mejupụtara n'ihe gbasara mkpuchi TiN ọkọlọtọ site na 100 Celsius. A na-ekpuchi TiAlN na ngwa ngwa igbutu ọsọ dị elu nke a na-eji na igwe CNC maka ịme ihe nke siri ike dị elu yana n'ọnọdụ ọnwụ siri ike. TiAlN dabara adaba karịsịa maka ndị na-akpụ ihe na-egwe ọka monolithic siri ike, mkpọpu ihe, ntinye ngwaọrụ na ịkpụzi mma. Enwere ike iji ya na ngwa igwe akpọnwụ akpọnwụ ma ọ bụ dị nso.
