Fletcher, NC… October 28, 2013 Starting with high strength carbon steel alloy the top rings are coated using MAHLE’s patented HV385 thermal spray process accelerating the particles to supersonic speeds, fueled by pure oxygen and RP1 jet fuel. The HV385 coating exhibits superior bonding and wear characteristics suitable for daily driver to high output power adder applications. The second rings are Napier construction and the oil rings use the proven CP-20 design.
