Lub chrome-plated txheej muaj lub tawv tawv tawv. Ua raws li kev sib xyaw ua ke ntawm cov tshuaj plating thiab cov txheej txheem ua haujlwm, qhov nyuaj ntawm chrome-plated txheej ntawm lub tog raj kheej piston pas nrig tuaj yeem ncav cuag HRC58 ~ HRC62. Lub chromium-plated txheej muaj qhov ua tau zoo kub. Thaum rhuab hauv qab 500 ℃, tsis muaj qhov hloov pauv meej hauv qhov tseeb thiab tawv. Qhov kub siab tshaj 500 ℃ pib ua rau oxidize thiab discolor, thiab lub hardness pib poob qis thaum kub siab tshaj 700 ℃. Kev sib txhuam coefficient ntawm chrome txheej yog me me, tshwj xeeb yog cov txhuam kev sib txhuam kom qhuav, uas yog qis tshaj plaws ntawm txhua cov hlau. Yog li no, chromium-plated txheej ntawm lub tog raj kheej piston pas nrig muaj hnav zoo tsis kam. Lub chromium txheej muaj tshuaj lom neeg ruaj khov. Nws tsis muaj kev cuam tshuam rau hauv alkali, sulfide, nitric acid thiab feem ntau cov organic acids, tab sis nws tuaj yeem yaj hauv halogen acid (xws li hydrochloric acid) thiab sulfuric acid. Yog li no, chrome-plated txheej ntawm lub tog raj kheej piston pas nrig muaj kev txhim kho zoo corrosion.
