World's Sl~ipperliestSolid The Guinness Book of World Records lis Is a patented dry-fil.m lubricant from General Magllaplate Corp. as the material with the lowest coefficient of friction (static and dynamic) of any solid. Hl-T-LUBE was invented in the 19505 for use in fighter aircratt, The lubricant was further developed for NASA in the 1960s to be applied to the mating surfaces of critical moving parts in space vehicles. Parts treated with ID- T-LUBE can operate in extreme temperatures (-360"F to +WOO"F). vacuum a:nd high radiation I j environments, maintainjng a coefficient of friction of 0,03 while withstanding compression load in exees of l50,000 psi. ID-T-LUBE i made up of five layer of metals and alloys that are electrodeposited and pennanenLly bonded to the substrate metal. It.can be applied to steel. stainles steel, copper, copper alloys Q[ aluminum. Typical applications include gears, rollers, bearings, pistons engines and other movingparts. The 1998 edition of The IGuinne s Book feature an interview with HJ-T-LUBE inventor Dr. Charles P: Covino, who. describes how somelimes luck is better than design. "l put five materials together and composited them into a lubricant. And it worked the first time." Covino said.
