420 SS(Stainless Steel) thermal spray waya chinhu chemhando yepamusoro chakagadzirirwa kushandiswa kwearc spraying. Inozivikanwa nekunakisisa corrosion resistance, kuomarara kwepamusoro, uye kunaka kupfeka kuramba, 420 SS isimbi isina tsvina ine martensitic inopa kuchengetedzwa kwakasimba kwepamusoro. Waya iyi inowanzoshandiswa mumaindasitiri akadai se petrochemical, kugadzirwa kwemagetsi, mota, uye zvemugungwa kusimudzira kusimba uye hupenyu hwezvinhu zvakakosha. Iyo 420 SS yekupisa yekupfapfaidza waya yakanakira maapplication anoda yakaoma, isingapfeki peyiti ine pakati nepakati corrosion resistance.
Kugadzirira kwepamusoro kwakakosha kuti uwane mibairo yakakwana ne420 SS thermal spray waya. Nzvimbo ichaputirwa inofanira kucheneswa zvine hungwaru kubvisa zvinosvibisa zvakaita segirisi, mafuta, tsvina, uye maokisi. Grit blasting nealuminium oxide kana silicon carbide inokurudzirwa kuti iwane kushata kwepamusoro kwe50-75 microns. Nzvimbo yakachena uye yakaomeswa inosimudzira kunamatira kweiyo thermal spray coating, zvichiita kuti kuve nekuvandudza kushanda uye hupenyu hurefu.

420 SS thermal spray waya ndiyo mhinduro yakanakisa yekusimudzira zvimiro zvepasi zvezvikamu zvakafumurwa kupfeka uye pakati corrosion. Kuomarara kwayo kwepamusoro uye kushomeka kwakanaka kunoita kuti ive yakakodzera kune zvikumbiro zvinoda jira rinogara uye rinogara kwenguva refu. Nekushandisa 420 SS thermal spray waya, maindasitiri anogona kuvandudza zvakanyanya hupenyu hwebasa uye kuvimbika kwemidziyo yavo uye zvikamu.
