Umphandle womsesane wepiston udla ngokugqunywa ukuze kuphuculwe iimpawu zokusebenza zeringi, ezinjengokutshintsha iimpawu zokungqubana okanye ukuqhawuka komphezulu. Ezinye iingubo, ezifana neengubo zokubeka ezifana nomzimba okanye iikhemikhali zokubeka umphunga, zihlala ziphucula iimpawu zokufakwa kweringi.

I-Alu-coat yi-copper enganyibilikiyo esekwe kwi-alumina, eyaphuhliswa ngasekupheleni kweminyaka yee-1990 ukunciphisa ixesha lokuphumla kweenjini ezintsha ze-MAN B & W MC.

I-MAN Diesel iye yazisa i-aluminium yokugqoka esekelwe kwiimpawu ezisebenzayo zokugijima kunye ne-semi-laning linings. Amava abanzi kunye ne-100% izinga lempumelelo yenza i-alu-coat ibonakale. I-1 yokuqhuba inketho yokwaleka. I-Alu-coat inciphisa ixesha lovavanyo kwaye idala ixesha elikhuselekileyo nelithembekileyo lokuqhawula. Namhlanje, amakhonkco agqunywe nge-aluminiyam asetyenziswa kwiinjini ezintsha nakwii-injini ezindala ezine-honing kunye ne-semi-honing bushings. Ukugquma kwe-aluminiyam kwakhona kunciphisa ukusetyenziswa kweoli ye-cylinder ngexesha lokuqhekeza.

I-Alu-coat yi-semi-soft thermal coat kunye nobukhulu obumalunga ne-0.25 mm. "Yayipeyintiwe" kwaye ikhangeleka irhabaxa, kodwa ngokukhawuleza yenza umphezulu ogudileyo ojikelezayo.

I-matrix ethambileyo kwi-coating ibangela ukuba izinto ezilukhuni ezinganyibilikiyo ziphumele kumphezulu weringi kwaye zisebenze kumphezulu obalekayo we-liner ngendlela erhabaxa kancinane. I-matrix isenokusetyenziswa njengesithinteli sokhuseleko ukuthintela iingxaki zokuqala zokukrazula phambi kokuba kugqitywe ukuqhekezwa.

Iinzuzo zokubuyisela kwakhona zininzi. Xa ifakwe kwi-bushings esetyenzisiweyo ngaphambili, i-aluminium yokugqoka ayigcini nje ukuphelisa ukuhamba kwexesha leringi yepiston. Olu gquba lukwabonelela ngomda wokhuseleko olongezelelweyo xa ujongene nemiba yokusebenza. Le nkqubo idla ngokuthatha iiyure ezingama-500 ukuya kuma-2,000. Isiphumo esirhabaxa kancinci samakhonkco episton agqunywe nge-aluminiyam siwenza alungele ukutshintshela amakhonkco episton asele enxilile ngokunxibelelene nokulungiswa ngokutsha kwepiston. Iilayini ezineringi ezinxibileyo zihlala zibonisa iimpawu zamabala epeyinti kunye / okanye ukuvuthela okunemingxuma kunye nokukhazimliswa. I-Alu-coat ibangela ukuguga kwe-lining egugileyo kwisikali se-microscopic, edla ngokwaneleyo ukuphinda kwakhiwe isakhiwo esibalulekileyo sokuvula i-lining, eyona nto ibalulekileyo kwi-tribology ye-lining ye-oyile // i-piston ring system.
