NiCr 80/20thermal spray hlauyog cov khoom siv zoo tsim rau kev siv arc txau. Cov hlau no yog tsim los ntawm 80% npib tsib xee thiab 20% chromium, ua rau nws yog ib qho kev xaiv zoo heev rau kev tsim cov coatings uas yuav tsum tau ua kom kub-resistant, corrosion resistance, thiab oxidation kuj. NiCr 80/20 yog dav siv nyob rau hauv ntau yam lag luam, suav nrog aerospace, lub zog tsim, petrochemical, thiab kev tsim khoom, los tiv thaiv thiab kho qhov chaw, txhim kho kev hnav tsis kam, thiab txuas ntxiv lub neej ntawm cov khoom tseem ceeb. Nws qhov kev ua tau zoo tshaj plaws nyob rau hauv ib puag ncig hnyav ua rau nws muaj kev txhim khu kev qha rau kev thov kev thov.
Kev npaj kom zoo yog qhov tseem ceeb kom ua tiav cov txiaj ntsig zoo nrog NiCr 80/20thermal spray hlau. Qhov saum npoo yuav tsum tau coated yuav tsum tau tu kom huv si kom tshem tawm cov kab mob xws li roj, roj, av, thiab oxides. Grit blasting nrog aluminium oxide lossis silicon carbide yog pom zoo kom ua tiav qhov roughness ntawm 50-75 microns. Ua kom lub ntsej muag huv thiab roughened txhim khu cov adhesion ntawm thermal spray txheej, ua rau kev txhim kho kev ua tau zoo thiab kev ua haujlwm ntev.
