Gịnị mere anyị ji eche na titanium alloy bụ ihe siri ike maka igwe? N'ihi enweghị nghọta miri emi nke usoro nhazi ya na ihe omume ya.
1. Mmetụta anụ ahụ nke Titanium Machining
Mbelata ike nke titanium alloy nhazi bụ naanị ntakịrị elu karịa nke ígwè nwere otu ike ahụ, ma ihe anụ ahụ nke nhazi titanium alloy dị mgbagwoju anya karịa nke nhazi ígwè, nke na-eme ka titanium alloy na-eche ihe isi ike ihu.
Thermal conductivity nke ọtụtụ titanium alloys dị nnọọ ala, naanị 1/7 nke ígwè na 1/16 nke aluminum. Ya mere, okpomọkụ a na-emepụta na usoro nke ịkpụ titanium alloy agaghị ebufe ngwa ngwa na workpiece ma ọ bụ wepụ ya site na ibe, ma a ga-akwakọba na ebe a na-egbutu, na okpomọkụ a na-emepụta nwere ike ịdị elu dị ka 1000 Celsius C, na-eme ka ọ dị elu. ịcha ọnụ nke ngwá ọrụ na-eyi, ịgbawa na ịnwụ ngwa ngwa. Mwube ọnụ na-ewuli elu, ọdịdị ngwa ngwa nke akụkụ ndị na-eyi, n'aka nke ya na-eme ka okpomọkụ dịkwuo elu na mpaghara ịkpụ, na-ebelata ndụ ngwá ọrụ.
Okpomọkụ dị elu nke a na-emepụta n'oge usoro ịkpụ na-ebibikwa iguzosi ike n'ezi ihe nke akụkụ titanium alloy, na-eme ka mbelata nke geometric ziri ezi nke akụkụ ahụ yana ihe na-eme ka ọrụ sie ike nke na-ebelata ike ọgwụgwụ ya.
Mgbanwe nke alloys titanium nwere ike ịba uru maka ịrụ ọrụ akụkụ, ma n'oge ịcha, nrụrụ na-agbanwe agbanwe nke workpiece bụ ihe dị mkpa na-akpata ịma jijiji. Nrụgide ịkpụ na-eme ka ihe arụ ọrụ nke "elastic" hapụ ngwá ọrụ ahụ ma weghachite ya, nke mere na esemokwu dị n'etiti ngwá ọrụ ahụ na ihe na-arụ ọrụ dị ukwuu karịa ihe nkwụsị. Usoro esemokwu ahụ na-ebutekwa okpomọkụ, nke na-eme ka nsogbu nke adịghị ike thermal conductivity nke titanium alloys ka njọ.
Nsogbu a na-akawanye njọ mgbe a na-edozi akụkụ ndị nwere mgbidi ma ọ bụ nke yiri mgbanaka na-adị mfe nrụrụ. Ọ bụghị ọrụ dị mfe ịhazi akụkụ titanium alloy mkpa nwere mgbidi na nha nha anya nke a na-atụ anya ya. N'ihi na mgbe ngwá ọrụ na-akwapụ ihe ndị na-arụ ọrụ, nrụrụ mpaghara nke mgbidi dị mkpa agafeela ihe dị iche iche na-agbanwe agbanwe iji mepụta nrụrụ plastik, na ike ihe na ike na njedebe na-abawanye nke ukwuu. N'oge a, machining na mbụ kpebisiri ike igbubi ọsọ na-adị oke elu, nke na-eduga n'ihu na-egbusi ngwá ọrụ.
"Okpomọkụ" bụ "onye mere mpụ" maka ihe isi ike nke nhazi titanium alloys!
2. Nkà na ụzụ nkà maka nhazi titanium alloys
N'ịghọta usoro nhazi nke titanium alloys, yana ahụmahụ gara aga, isi ihe ọmụma banyere nhazi titanium alloys bụ nke a:
(1) Inserts na nti nkuku geometry iji belata ọnwụ ike, igbutu okpomọkụ na deformation nke workpiece.
(2) Nọgide na-eri nri mgbe niile ka ịzenarị ike nke workpiece. Ngwá ọrụ kwesịrị ịdị na steeti nri mgbe niile n'oge usoro ịkpụ. Ọnụ ego mbelata radial ae kwesịrị ịbụ 30% nke radius n'oge egwe ọka.
(3) A na-eji mmiri dị elu na-eme ka nrụgide dị elu na nnukwu mmiri na-agbapụta iji hụ na nkwụsi ike nke okpomọkụ nke usoro nhazi ahụ ma gbochie elu ọrụ ahụ site na mmebi na mmebi ngwá ọrụ n'ihi oke okpomọkụ.
(4) Debe ọnụ ọnụ nke agụba ahụ dị nkọ, mma na-adịghị mma bụ ihe na-akpata ọkụ ọkụ ma na-eyi, nke nwere ike iduga n'ụzọ dị mfe na ọdịda nke mma.
(5) Nhazi na steeti dị nro nke titanium alloy dị ka o kwere mee, n'ihi na ihe ahụ na-esiwanye ike ịhazi mgbe ọ gbasasịrị, ọgwụgwọ okpomọkụ na-eme ka ike nke ihe dịkwuo mma ma na-eme ka ọ dịkwuo mma.
(6) Jiri nnukwu radius ma ọ bụ chamfer imi dị ka o kwere mee n'ime mbepụ. Nke a nwere ike ibelata ike ịkpụ na okpomọkụ n'ebe ọ bụla ma gbochie nkwụsịtụ mpaghara. Mgbe a na-egwe ọka titanium alloys, n'etiti ndị na-egbutu mkpụrụ osisi, ọsọ nke ịkpụ nwere mmetụta kachasị na ndụ ngwá ọrụ vc, na-esote ọnụọgụ radial (milling deep) ae.

3. Na-edozi nsogbu nhazi titanium na-amalite site na agụba
Uwe akwa agụba nke na-eme n'oge nhazi alloy titanium bụ uwe mpaghara nke azụ na ihu n'akụkụ omimi nke ịkpụ, nke a na-emekarị site na oyi akwa siri ike hapụrụ site na nhazi gara aga. The chemical mmeghachi omume na mgbasa n'etiti ngwá ọrụ na workpiece ihe na a nhazi okpomọkụ karịa 800 Celsius C bụkwa otu n'ime ihe mere e guzobere uzo iyi. N'ihi na n'oge nhazi, ndị titanium molekul nke workpiece na-agbakọta n'ihu agụba, na-"welded" na agụba n'okpuru elu nrụgide na elu okpomọkụ, na-akpụ wuru ọnụ. Mgbe ọnụ na-ewuli elu na-apụ apụ site na njedebe nke ịkpụ, ọ na-ewepụ ihe mkpuchi carbide nke ntinye, ya mere titanium machining chọrọ ihe ntinye pụrụ iche na geometries.
4. Ngwá ọrụ ngwá ọrụ kwesịrị ekwesị maka titanium machining
Ihe na-elekwasị anya na nhazi alloy titanium bụ okpomọkụ. A ghaghị fesa nnukwu mmiri mmiri na-eme ka ọ dị elu na njedebe nke oge na nke ziri ezi iji wepụ okpomọkụ ngwa ngwa. Enwere ihe owuwu pụrụ iche nke ndị na-eji igwe ihe eji eme ihe maka nhazi titanium alloy n'ahịa.
