Rising fuel prices and more stringent requirements in the field of the vehicle emissions such as nitrogen oxides, particulate matter and carbon dioxide will increase the pressure on the engine manufacturers to utilize technologies which contribute to a reduction in these emissions. As a result, interest in cylinder surface coatings has increased considerably in the last few years, also in the SUMEBore® coating solution from Sulzer Metco. SUMEBore coatings are applied by a powder-based air plasma spraying (APS) process. Such an APS process is very flexible and can also process materials to which wire-based methods do not have any access, particularly metal matrix composites and pure ceramics. The compositions can be tailored to the specific challenges in an engine, e.g., excessive abrasive wear, scuffing, corrosion caused by adulterated fuel or high exhaust gas recirculation (EGR) rates, etc.
