thumbs up signHi, folks. Defric is a trade name for one brand of solid film lubricants and related coatings which seem to be available from Nihon Parkerizing of Tokyo, Japan, which appears to have subsidiaries around the world. Please google for further info.

This site's supporting advertisers cheerfully make the site available for technical discussions and camaraderie, but they would justifiably have a problem if the readers, instead of contacting them about their dry film lubricants and coating needs, ask them to bear the cost of posting detailed distributorship info for their competitors who don't support the site :-)

A. The coating thickness allowance must be calculated and incorporated in the drawing of the component on which the coating has to be applied.

Molybdenum disulfide vs. manganese phosphate coatings

June 3, 2014

Q. What is the difference between manganese phosphate coating and Defric coating? Is manganese coating recommended for pistons of HFO [heavy fuel oil] engines?

Molybdenum Disulfide

Phosphate Conversion Coating

A. Hi Ahmad. Defric is only a trade name and does not specify the technology of the coating. But we assume that you are referring to molybdenum disulfide coatings? These are "dry film lubricants" rather similar to graphite in function.

Yes, manganese phosphate coatings are used on piston rings and other lubricated machine parts, and one of their primary uses is as a "break-in" coating. The phosphate is granular, soft, and oil-retaining -- providing a useful degree of lubrication before oil gets to the parts.
