Wear Resistance

The tell-tale signs of wear can spell real trouble for an engine’s performance. Are you having issues with leakage between the valve and seat?  Or are your fuel emission and fuel economy goals for the engine not being met?  You probably know that wear resistance is not related to a material’s intrinsic property, but rather it is the way one material responds to multiple variables, including the material properties of another part.  This is a common issue we face with our customers and their engines, especially with new designs and higher temperatures and pressures being employed.  Through decades of testing and analysis we have developed a proprietary library of wear correlation data between common valve and seat materials, including the most recent patented cast alloys from us and other makers.  Did you know that there are several ways to mitigate wear beside simply changing the alloyed material?  In fact, if you are using dryer fuels such as natural gas, particulate lubrications or coatings may be necessary to help offset the impact of the fuel creating a harsher environment for wear to propagate.
