Iyo yekunze yemhete yepiston inowanzoputirwa kuti ivandudze mashandiro emhete, senge nekushandura frictional kana abrasion maitiro epamusoro. Mamwe machira, akadai semachira ekuisa senge emuviri kana kemikari vapor deposition coatings, anowanzo kuvandudza maitiro ekuisa mhete.

Alu-coat ndeye isinganyunguke mhangura-yakavakirwa coating yakavakirwa paaluminium, iyo yakagadziridzwa mukupera kwema1990s kuderedza uptime yeitsva MAN B & W MC injini.

MAN Diesel yakaunza aluminium coating yakavakirwa pakushanda-mune maitiro ekumhanya-mukati uye semi-akapfeka linings. Zvakawanda ruzivo uye 100% budiriro mwero inoita kuti alu-coat ive pachena. 1 inomhanya-mukati coating sarudzo. Alu-coat inoderedza nguva yekuedza uye inogadzira yakachengeteka uye yakavimbika yekupwanya-munguva. Nhasi, zvindori zvakavharwa nealuminium zvinoshandiswa mumainjini matsva uye mumainjini ekare ane honing uye semi-honing bushings. Iyo aluminium coating zvakare inoderedza kushandiswa kwemafuta ecylinder panguva yekupwanya.

Alu-coat is a semi-soft thermal spray coating ine ukobvu hunosvika 0.25 mm. Yakanga "yakapendwa" uye yairatidzika kunge yakaoma, asi yakakurumidza kuumba nzvimbo yakatsetseka yakatenderedzwa.

Iyo matrix yakapfava pajasi inokonzera yakaoma isinganyunguriki zvinhu kuti ibude pamusoro peinomhanya pamusoro perin'i uye inobata pamusoro pekumhanya kwe liner nenzira inotyisa zvishoma. Iyo matrix inogona zvakare kushandiswa sechivharo chekuchengetedza kudzivirira matambudziko ekutanga abrasion kusati kwapera.

Zvakanakira retrofitting zvakawanda. Kana yaiswa mumabhushi akashandiswa kare, iyo aluminium coating haingobvisi chete kumhanya-munguva yepiston mhete. Uku kupfekedza kunopawo imwe chengetedzo muganho kana uchibata nenyaya dzekushanda. Izvi zvinowanzotora maawa 500 kusvika ku2,000. Iyo zvishoma abrasive mhedzisiro yealuminium-yakavharwa piston mhete inoita kuti ive yakakodzera kutsiva yakasakara mhete dzepiston zvine chekuita nekugadziriswa kwepiston. Lining dzine mhete dzinowanzoratidza zviratidzo zvependi uye / kana kuputika-kubuda kune zvishoma uye kukwenenzverwa. Alu-jasi inokonzeresa kupfeka-kupfeka kwembatya pachiyero chemicroscopic, icho chinowanzo kukwana kuvakazve yakakosha yekuvhura chimiro cheiyo lining, iyo yakakosha kune tribology ye lining / oiri / piston ring system.
