Titanium alloys tau siv dav hauv kev lag luam aerospace, tub rog, thiab pej xeem kev lag luam vim lawv qhov tshwj xeeb lub zog-rau-hnyav piv, tiv thaiv corrosion, siab kub, thiab biocompatibility. Txawm li cas los xij, qhov tsis tshua muaj qhov tawv tawv thiab qhov tsis txaus hnav tsis zoo ntawm titanium alloys tau ua rau muaj kev txwv hauv ib puag ncig tshwj xeeb. Txhawm rau kov yeej cov teeb meem no, cov kws tshawb fawb tau tsim ntau yam kev kho mob saum npoo av los txhim kho qhov ua tau zoo ntawm titanium alloys.
Ib txoj hauv kev zoo yog kev kho oxidation saum npoo, uas suav nrog kev tsim cov oxide zaj duab xis los txhim kho lubricity thiab txo cov adhesion thaum lub sij hawm kos duab. Txheej kev kho mob xws li graphite emulsion txheej thiab ntsev-lime txheej muab lubrication thiab tiv thaiv oxidation, txhim kho cov khoom nto. Kev kho mob fluorophosphate suav nrog txheej txheej nrog cov yeeb yaj kiab hloov kho raws li cov khoom siv roj nplua nyeem kom ua tiav kev sib txhuam qis thiab hnav tsis kam.
Lwm txoj hauv kev yog hlau zaj duab xis plating, qhov twg txheej txheej ntawm cov hlau xws li tooj liab, chromium, npib tsib xee, lossis tin tau tso rau ntawm titanium alloy nto kom txo tau cov hlau ncaj qha thaum kos duab, yog li txo qhov adhesion. Kev kho mob boriding muaj immersing titanium alloy xov hlau nyob rau hauv ib qho kev daws teeb meem uas muaj KFB4, BaCl2, thiab NH4NO3 los tsim ib txheej fluoroborate rau ntawm qhov chaw, ua raws li los ntawm kev siv txhuas disulfide ua lub lubricant thaum txias txias.
Kev kho tshuaj hloov pauv tshuaj ua cov yeeb yaj kiab hloov dua siab tshiab rau ntawm titanium alloy nto, ua haujlwm raws li cov txheej txheem lubrication uas adsorbs lubricants, ua rau cov npoo du tom qab ntau cov txheej txheem kos duab. Xaiv cov roj nplua nyeem uas tsim nyog xws li cov hmoov xab npum, graphite emulsion, thiab cov khoom sib tov ntawm xab npum hmoov thiab lwm yam ntaub ntawv uas zoo wettability thiab thermal stability yog qhov tseem ceeb.
Laser nto kev kho mob zoo li laser cladding, alloying, thiab quenching hloov qhov chaw microstructure los txhim kho hnav tsis kam, corrosion kuj, thiab hardness yam tsis muaj kev cuam tshuam lub hauv paus zog ntawm titanium alloys. Micro-arc oxidation yog cov txheej txheem eco-phooj ywg uas loj hlob cov yeeb yaj kiab ceramic hauv qhov chaw ntawm titanium alloy qhov chaw, muab cov corrosion zoo heev thiab hnav tsis kam.
