Abstract:

Steel cylinders were coated with 0.05-0.1 mm layers of machine oil, diesel oil, motor oil, automobile lubricant, or glycerol. The cylinders were heated at 310 degrees for 20-100 min. cooled and coated with a film of polycaprolactam I. The adhesive strength A between I and the cylinder was at a maximum, i.e. 375 kgsq cm when the cylinders were coated with machine oil and heated during 40 min. the control samples, which were carefully degreased before the application of I, and A equals 50 kgsq cm. The increase of A is due to the polymn. of the oil on the steel surface during heating. The obtained polymer had better A to I than steel. Motor oils, which contain antioxidants and detergents, do not polymerize readily and thus do not increase A appreciably. Author
