SURFACE FINISH

Kurapa kwekupisa

Kupisa kupisa imhando yesimbi yekupisa tekinoroji. Izvo zvinyorwa zvishoma nezvishoma zvinowana chimiro chinotarisirwa uye kushanda kuburikidza nekupisa, kuchengetedza kupisa uye kutonhora mumamiriro akasimba. Metal kupisa kurapwa maitiro anogona kukamurwa kuita zvikamu zvitatu: yakazara kupisa kurapwa, kupisa kwepamusoro kurapwa uye kemikari kupisa kurapwa. Muzhinji, chimiro chezvikamu uye chimiro chemakemikari chese hachichinji. Nekushandura microstructure yemukati yezvikamu, kana kushandura kemikari yepamusoro pezvikamu, kushandiswa kwekushandiswa kwezvikamu zvinogona kuvandudzwa. Chimiro chayo ndechekuvandudza hutano hwemukati hwezvikamu, izvo zvinowanzosaoneka.

Oxidized Black and Black Anodized

Oxidized Black kurapwa inzira yakajairika yemakemikari epamusoro kurapwa. Nheyo yacho ndeyekuburitsa firimu reoxide pane simbi pamusoro kuti iparadzanise mhepo uye kuzadzisa chinangwa chekudzivirira ngura. Blackening kurapwa inogona kushandiswa kana chitarisiko chinodiwa chisina kukwirira. Kurapa kwepamusoro-soro kwesimbi kunonziwo blued. Anodizing ndiyo electrochemical oxidation yesimbi kana alloys. Aluminium uye alloys ayo anoumba layer ye oxide firimu pane aruminiyamu zvigadzirwa (anode) pasi pechiito chekushandiswa ikozvino pasi pe electrolyte inoenderana uye chaiwo maitiro emamiriro. Kana anodizing isina kutaurwa, inowanzoreva sulfuric acid anodizing.

Polishing

Kupukuta kunoreva kushandiswa kwemakanika, kemikari kana electrochemical mhedzisiro kuderedza kushata kwepamusoro kwechishandiso kuti uwane inopenya uye yakatsetseka. Iko kushandiswa kwezvishandiso zvekupolisha uye abrasive particles kana imwe polishing media kugadzirisa pamusoro peiyo workpiece.

Nitriding

Nitriding treatment inoreva makemikari ekupisa kupisa umo maatomu enitrogen anopinda pamusoro pechishandiso mune imwe svikiro pane imwe tembiricha. Zvigadzirwa zveNitrided zvine zvakanakisa kupfeka kuramba, kuneta kuramba, corrosion resistance uye yakakwirira tembiricha kuramba. Yakajairwa nitrided simbi ine aruminiyamu inogona kuwana kuomarara kwepamusoro uye yakakwirira kupfeka-inodzivirira pamusoro pe layer mushure mekuita nitriding, asi iyo yakaomeswa layer ine brittle. Kusiyana neizvi, chromium-ine yakaderera-alloy simbi ine yakaderera kuomarara, asi iyo yakaomeswa dhizaini yakanyanya kuomarara, uye pamusoro payo ine shongedzo yekupfeka uye kusagadzikana kwekuora.
