Nā Pono Mechanical Titanium Alloy
ʻO ka hoʻohana ʻana i ka mahana he mau haneli mau kiʻekiʻe ma mua o ke alumini alumini, i ka mahana wela hiki ke mālama i ka ikaika i koi ʻia, hiki ke 450 ~ 500 ℃ wela no ka manawa lōʻihi e hana i kēia mau mea ʻelua titanium alloy ma ka laulā o 150 ℃ ~ 500 ℃ Loaʻa ka ikaika kikoʻī kiʻekiʻe loa, a ua emi nui ka ikaika kikoʻī o ka alumini alumini ma 150 ℃. Hiki i ka mahana hana o ka titanium alloy ke hiki i 500 ℃, a ʻo ka alumini alumini ma lalo o 200 ℃. ʻO ka pale ʻana i ka corrosion maikaʻi.
ʻOi aku ka maikaʻi o ka pale ʻana o ka titanium alloy ma mua o ke kila kila ke hana ʻo ia i loko o ka lewa a me ka wai kai. ʻOi aku ka ikaika o ka pale ʻana i ka corrosion pitting, corrosion acid a me ka corrosion stress; Loaʻa iā ia ke kūpaʻa corrosion maikaʻi loa i ka alkali, chloride, chlorinated organic goods, nitric acid, sulfuric acid, a me nā mea ʻē aʻe.
Hiki i ka Titanium alloy ke mālama i kona mau waiwai mechanical ma nā wela haʻahaʻa a haʻahaʻa loa. Hiki i nā huila Titanium me ka maikaʻi haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, e like me TA7, hiki ke mālama i kekahi plasticity ma -253 ℃. No laila, ʻo ka titanium alloy kekahi mea koʻikoʻi haʻahaʻa haʻahaʻa. He kiʻekiʻe ka hana kemika o ka titanium, a me ka lewa i O, N, H, CO, CO₂, wai mahu, amonia a me nā hopena kemika ikaika ʻē aʻe. Ke ʻoi aku ka nui o ke kalapona ma mua o 0.2%, e hana ʻo ia i ka TiC paʻakikī i ka titanium alloy;
Ma ka wela kiʻekiʻe, e hana pū ka pilina me N i ka ʻili paʻakikī o TiN; Ma luna o 600 ℃, hoʻopaʻa ka titanium i ka oxygen e hana i kahi papa paʻakikī me ka paʻakikī kiʻekiʻe; E hoʻokumu ʻia ka papa embrittlement i ka wā e piʻi ai ka ʻike hydrogen. ʻO ka hohonu o ka ʻili paʻakikī paʻakikī i hana ʻia e ka lawe ʻana i ke kinoea hiki ke hōʻea i 0.1 ~ 0.15mm, a ʻo ke degere paʻakikī ʻo 20% ~ 30%. Nui nō hoʻi ka pili kino o ka titanium, maʻalahi e hana i ka adhesion me ka ʻili friction.
ʻO ka thermal conductivity o ka titanium λ=15.24W/ (mK) ma kahi o 1/4 o ka nickel, 1/5 o ka hao, 1/14 o ka alumini, a ʻo ka conductivity wela o nā ʻano like ʻole o ka titanium alloy he 50% ka haʻahaʻa ma mua o kēlā. o ka titanium. ʻO ka modulus elastic o ka titanium alloy e pili ana i ka 1/2 o ke kila, no laila ʻilihune kona rigidity, maʻalahi i ka deformation, ʻaʻole pono e hana ʻia me ke koʻokoʻo liʻiliʻi a me nā ʻāpana ʻāpana ʻāpana, ʻoki ʻia ka nui o ka rebound o ka ʻili, ma kahi o 2 ~ 3 mau manawa. o ke kila kuhiliʻole, ka hopena i ka hakakā ikaika, adhesion, hoʻopaʻa lole ma hope o ka ʻili o ka mea hana.
