Article on "Advances in Surface Engineering - Pistons, Piston Rings" by Dr. R. Mahadevan, Group Technology Director - India Pistons Ltd
(As published in MOBILITY ENGINEERING - A quarterly publication of SAE International & SAE India, December 2013 issue)

Excerpts from the Article
"Newer materials with improved properties can enhance the properties of the working surfaces of cylinder components for the demands of increased temperatures, pressures, and corrosive atmospheres and still satisfy performance and life requirements."

"Cylinder components, which have to bear the brunt of increased temperatures, pressures, and corrosive atmosphere and still satisfy performance and life requirements, have benefited greatly from recent advances in surface engineering."

"The piston ring peripheral surface and cylinder bores have received special attention from designers for improvement of their running properties."

Surface Engineering - Diamond Coatings

"Diamond-like carbon coatings (DLC) have been applied to piston pins, piston ring peripheries, and cylinder bores for improving wear resistance. Physical-vapor deposition (PVD), plasma-assisted chemical vapor deposition (CVD), or a combination of both have been employed for applying these amorphous carbon coatings."
