Experimental Study of Frictional Vibrations Under Dry Friction Conditions

Recent advances in the commercial exploitation of electrospark coatings have focused on improving surface roughness by depositing Ti, Mo, V, or W over an interlayer of Cu, Sn, Pb, or Cd on the top of a tool steel material. This paper presents results of a systematic pin-on-disk experimental study of different type bilayer coatings (Cu–Sn/bronze, bottom layer; Ti and Mo, top layer) deposited on a Type 45 steel. The results are discussed in terms of friction coefficients obtained under different dry-friction conditions (speeds ranging from 0.3m∕sto0.8m∕s, and pressures ranging from 10Nto40N). An additional focus is on scuffling resistance of faces in friction, microhardness and surface roughness of coated items, and the competitive advantage of using advanced surface coatings.

An experimental study, including three experimental devices, is presented in order to investigate dry friction phenomena in a wide range of sliding speeds for the steel on steel contact. A ballistic setup, with an air gun launch, allows to estimate the friction coefficient between 20 m/s and 80 m/s. Tests are completed by an adaptation of the sensor on a hydraulic tensile machine (0.01 m/s to 3 m/s) and a pin-on-disk tribometer mounted on a CNC lathe (1 to 30 m/s). The interactions at the asperity scale are characterized by a white light interferometer surface analysis.

Elliptical Area

This paper describes an experimental study on the dry friction-creep phenomenon. The study has been carried out on a test-rig. The simulated wheel has an elliptical area of contact similar to the actual locomotive wheel and is made of a 1070 plain carbon steel. The testing was conducted with variable contact stresses up to approximately 200,000 psi and equivalent speeds of approximately 5 miles per hour. The results of the test show that all the different creep-adhesion curves obtained by changing the normal loads can be reduced to one single dimensionless curve. This can be achieved if the actual nominal area of contact experimentally measured, is introduced in the corresponding expressions. A law of constancy of the product of the creep times the area of contact for dry, clean contact surfaces and a constant value of adhesion and normal load is presented.

Lubricating Properties

Abstract The results have been presented of an experimental study of the tribological behavior of diamond-like carbon coatings (DLC) doped with chromium and molybdenum obtained by reactive magnetron sputtering. The effect of alloying with these metals on the tribological characteristics of boundary lubrication of a DLC coating/steel contact has been studied for the case of three model lubricants (inactive, surfactant, and chemically active). It has been shown that doping with chromium and molybdenum improves both the tribological characteristics of coatings under dry friction and the lubricating properties of the model oils, while alloying with molybdenum provides lower coefficients of friction and less wear at dry and boundary friction than alloying with chromium.
