Iindidi eziphambili zeepleyiti ze-titanium

Ngokwemigangatho eyahlukeneyo, iipleyiti ze-titanium zinokwahlulwa zibe ziindidi ezininzi. Ngokokwakheka kweekhemikhali, iipleyiti ze-titanium zahlulwe ikakhulu ngamacandelo amabini: iipleyiti zetitanium ezisulungekileyo kunye neepleyiti ze-titanium alloy. Iipleyiti ze-titanium ezicocekileyo zohlulwe ngokwamanqanaba afana ne-TA1, TA2, kunye ne-TA3 ngokwezihlambululo ezahlukeneyo. Ubunyulu buyancipha kwaye amandla ayanda ngokuthe ngcembe. Iipleyiti ze-titanium ezicocekileyo zineeplastiki ezilungileyo kunye neempawu ze-welding kwaye zihlala zisetyenziselwa izixhobo zekhemikhali kunye nokuhlobisa izakhiwo.

Iipleyiti ze-Titanium alloy zongeza ezinye izinto (ezifana ne-aluminium, i-vanadium, i-molybdenum, njl.) kwi-titanium ecocekileyo ukuphucula ukusebenza kwayo. Iipleyiti eziqhelekileyo ze-titanium alloy zibandakanya i-TC4 (Ti-6Al-4V), i-TC11 (Ti-6.5Al-3.5Mo-1.5Zr-0.3Si), njl. Inamandla amakhulu, ukumelana nobushushu obuhle kunye nokuxhathisa ukubola, kwaye isetyenziswa ngokubanzi kwi-aerospace kunye nezonyango. Amandla e-tensile ye-TC4 ye-titanium plate inokufikelela ngaphezu kwe-895 MPa, kwaye ubushushu bokusebenza bunokufikelela kwi-400 degree.

Ngokwenkqubo yemveliso, iipleyiti zetitanium zingohlulwa zibe zishushu{{0}iipleyiti eziqengqelekayo kunye nezibandayo{1}}eziqengqelekayo. Ashushu-iipleyiti eziqengqelekayo ziqengqeleka ngaphezulu kobushushu obuphinda bube yikristale, buqhele ukuba nobukhulu obungaphezulu kwe-3 mm, kwaye bomelele kwaye buqine. Abandayo -iipleyiti eziqengqelekayo ziqengqeleka kwiqondo lobushushu begumbi, zibhityile (zidla ngokuba ngaphantsi kwe-3 mm), zibe nomphezulu ogudileyo, kwaye zichaneke kakuhle. Ukongezelela, kukho iipleyiti ezidibeneyo ze-titanium, ezenziwe nge-welding eqhumayo okanye i-rolling titanium plates nezinye izinyithi (ezifana nentsimbi, i-aluminium, njl.). Zizo zombini ukuxhathisa i-titanium kunye namandla e-substrate, kwaye zihlala zisetyenziselwa izixhobo zemichiza kunye nobunjineli baselwandle.
