Turbine lubrication and fuel lines can experience extreme heat during shutdown. Temperatures of 300c or more can cause fuel and lubrication lines to develop carbon deposits which over time can build up, causing fuel starvation or lubrication failures. SilcoTek® CVD coatings, like SilcoKlean®, prevent carbon deposit formation, significantly extending maintenance cycles. Testing shows carbon deposition can be reduced by orders of magnitude when used with common fuel additives. (Data & image credit: "High Heat Sink Fuels Program" Patricia Pearce, Wright Patterson AFB)

Modern fuels (be it jet, diesel, or gasoline) can decompose and foul under extreme heat. With the advent of direct injection and modern turbine nozzles, exposure to combustion conditions result in increased carbon fouling, poor fuel spray and inefficient flame propagation during combustion. SilcoTek® coatings reduce carbon buildup on critical injection and fuel delivery flow paths, preventing fuel injector fouling and improving combustion efficiency and maintaining peak engine performance.

Turbochargers and exhaust intercoolers are exposed to extreme heat and exhaust particulates which can cause lubrication failures and exhaust EGR intercooler fouling. SilcoTek coatings reduce carbon fouling by preventing carbon formation and bonding to stainless steel and alloy surfaces. SilcoTek coatings prevent accumulation of carbon even under extreme combustion conditions found in IC engine pistons.

The coated piston (left) shows little to no fouling. The uncoated piston (right) shows significant carbon fouling.
Coating critical flow paths prevent carbon coking and fouling. SilcoTek coatings can be applied to glass, ceramic, quartz, stainless steel and steel alloy surfaces, improving engine performance and durability. Flow path components include:
