Ngokubanzi, umphezulu kunye nobuso besiphelo sendandatho yokuqala bufakwe nge-chrome, kunye nezinye iiringi zepiston nazo zinokufakwa nge-chrome. Amakhonkco amakhulu e-injini ye-diesel ye-piston ayi-chrome-plated, kunye ne-cylinder liners zi-chrome-plated. Okwangoku, i-chrome-ceramic composite coating piston ring iye yaphuhliswa, kwaye uvavanyo lubonisa ukuba ixabiso lokugqoka lingaphantsi kwesiqingatha se-piston ye-chrome-plated ring, kunye nomthamo wokugqoka we-cylinder liner ehambelanayo nayo iyancitshiswa.

Umaleko otshiziweyo weMolybdenum unokumelana nokunxiba okungcono, ukukopa kunye nokuxhathisa isilinda kune-chrome plating. I-Chrome-plated steel cylinder liner kunye ne-molybdenum-sprayed piston ring inokwenza i-friction pair elungileyo.

Iileya eziqhele ukusetyenziswa eziqinileyo kwimisesane yepiston yi-aluminiyam oxide, i-titanium oxide kunye ne-chromium oxide, ngakumbi i-aluminiyam titanate yokwambathisa.

Indlela yokufakelwa kwe-ion idibanisa izinto ezikhethiweyo zeekhemikhali kwi-bundle kwi-cylinder liner kunye ne-piston ring surfaces. Uluhlu lwe-ion olutofelweyo ludityaniswe nomphezulu we-cylinder liner kunye ne-piston ring, kwaye inefuthe elincinci kubunzima bomphezulu kunye nokuchaneka komlinganiso. Kukho ubukhulu becala i-plasma yokufakwa kwe-TiN yolwaleko losasazo, i-ion ion plating yefilimu enzima ye-CrN, i-ion carburizing enqabileyo yomhlaba njalo njalo. Iimvavanyo zibonisa ukuba ukucima kunye nokuthambisa iringi yepiston kunye nokufaka i-nitriding umphezulu we-ion zomhlaba ezinqabileyo kunokuphucula kakhulu ukuxhathisa ukunxitywa kweringi yepiston kwaye yandise kakhulu ubomi bayo benkonzo.

Unyango lokuthambisa umphezulu kukwenza iikhemikhali ifilimu ekhompawundi yesinyithi kumphezulu wentsimbi, intsimbi kunye nemathiriyeli yesinyithi yomgubo ukuze idlale indima yokuzithambisa. Kukho ubukhulu becala ukwakhiwa kwefilimu yonyango lwe-phosphating kunye ne-alkaline oxidation yonyango lokwenziwa kwefilimu, ezisetyenziselwa ukulalisa amakhonkco episton kunye nee-cylinder liners zeenjini ezincinci zokutsha zangaphakathi. Ukongeza, i-nitriding elulwelo kunye ne-nitriding ethambileyo inokuphucula ukuxhathisa ukunxitywa kwee-iron cylinder liners.

Ukuxhatshazwa kokugqoka kwesibini sokukhuhlana kuchaphazeleka yizinto ezahlukeneyo, ngoko ke umphezulu uyanda ukuphathwa ngokuxhatshazwa kwezinto ezininzi. Umzekelo: isisombululo somlilo kunye ne-sulfurizing, ukucima i-carburizing kunye ne-sulfurizing, i-nitriding ethambileyo kunye ne-sulfurizing, i-nitroxide kunye nokudibanisa i-chrome plating kunye ne-molybdenum spray.
