The process also opens up new possibilities for alloy selection. It is being tested on camshafts. This process is also being applied to cylinder bores. This results in lower friction, less wear, and a stiffening of the engine block. Look for results of this technology at the long speedways such as Daytona and Talladega.
Corrosion prevention is an utmost necessity in engines, especially in small aircraft engines.
Engines that sit for long periods of time without use can have water condense in them and corrosion can start. Also, the products of combustion are extremely corrosive. They can form compounds such as sulfuric acid and nitric acid. Corrosion sites are prime areas where fatigue cracks can initiate. The products of corrosion are also very abrasive.
