Cov yam ntxwv tseem ceeb

T800 yog ib qho ntawm feem ntau siv cobalt-raws li alloys. Nws qhov loj tshaj plaws yog qhov sib txhuam coefficient tsawg, thiab nws muaj kev hnav zoo heev, kev tiv thaiv corrosion thiab kub tsis kam.

T 800 cobalt-raws li alloys yog tsim los ntawm nyuaj intermetallic compound (Laves) theem dispersed nyob rau hauv ib tug softer eutectic los yog cov kua matrix. Lawv pom zoo hnav thiab qaug dab peg tsis kam, siab corrosion kuj thiab tshwj xeeb tshaj yog haum rau cov xwm txheej nyuaj lubrication. Kev hnav tsis kam ntawm Tribaloy alloys nyob ntawm qhov ntim feem pua ​​​​ntawm Laves theem.

Tribaloy T-800 yog tsim los tiv thaiv kub hnav thiab puas. Vim nws cov ntsiab lus siab chromium, nws muaj oxidation zoo heev thiab corrosion kuj. T-800 yog ib qho nyuaj thiab muaj kev hnav zoo dua li T-400.

T-800 pom zoo corrosion kuj nyob rau hauv acetic acid (50% concentration, boiling) thiab phosphoric acid (85% concentration, 66 ° C). Zoo heev corrosion kuj tseem pom nyob rau hauv sulfuric acid (5% concentration, 66 ° C).

Daim ntawv thov

T-800 yog siv dav hauv kev lag luam aerospace vim nws qhov kub thiab txias tsis kam, tshwj xeeb tshaj yog nyob rau hauv hardfacing ntawm aircraft cav turbine hniav. Tsis tas li ntawd, nws kuj yog siv los tsim lossis tsho loj ntau yam hauv qhov chaw hnav thiab corrosion, xws li bearings, cams, retaining rings, diesel piston rings, mechanical seals, bearings seats, valve trims thiab twj tso kua mis Cheebtsam.
