Abstract:
A protective coating system includes a coating having a composition that includes about 5-40 wt% of chromium, of about 5-35 wt% of aluminum, about 0.1-9 wt% of at least one of silicon, hafnium, or magnesium, about 0.05-2 wt% of a Group IIIB Periodic Table element, a non-zero amount less than 13 wt% of at least one noble metal selected from platinum, palladium, and gold, and a balance including nickel, cobalt or iron.
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.
Abstract:
The invention concerns a micro-machined device (10) for fluids comprising a substrate (12) with a flow conduit (14), a thin ductile layer (18) such as a pumping diaphragm or a diaphragm forming a check-valve. The thin layer (18) is a laminated metal sheet, preferably made of titanium and connected to the substrate (12) at the overlapping zone (20) of the flow conduit, by anodic welding. The invention is useful for producing a check-valve.
