    Abstract: An apparatus (100) includes a first component (102) having a first surface (106) and a second component (104) having a second surface (110). The first surface includes sputtered gold, and the second surface includes a stainless steel alloy. The first surface is configured to contact the second surface, and one of the components is configured to move against another of the components. The stainless steel alloy could consist of a UNS 21800/AISI Type S21800 metal. The sputtered gold could include ion sputtered gold, and the sputtered gold could have a thickness of about 1 micron. The first component could include a first blade (306) of an adjustable aperture mechanism, where the adjustable aperture mechanism also includes a second blade (308). The second component could include a first plate (310) of the adjustable aperture mechanism, where the adjustable aperture mechanism further includes a second plate (312). The blades can be configured to move within a space between the plates.

    Abstract: A piston for a diesel internal combustion engine including a crown portion at least partially formed of steel and having a combustion surface with a combustion bowl formed therein is provided. The combustion bowl presents a combustion bowl rim area, and a coating including at least one of a noble metal and a refractory metal is applied to substantially only the combustion bowl rim area. The coating is preferably applied in the areas of the combustion bowl rim area that are in line with the sprays of diesel fuel when the piston is in a top dead center position during operation of the engine.
