Abstract

Friction and scuffing behaviour of grey cast iron as influenced by the surface roughness under sparse lubrication conditions is studied. The studies are carried out on a three-shoe-on-disc machine under the conditions of parallel sliding. The experiments were conducted at three oil supply rates of 0.10, 0.22 and 0.36 μg/cm2 per contact obtained through a mist oiling system and with specimens of cast iron shoes of different roughness values, Ra, between 0.04 and 2.0 μm against a 0.55% C steel disc. In a step load procedure, the friction torque at the end of each load step and the scuffing load are the major parameters measured. Results of friction and scuffing behaviour as a function of roughness and oil supply rates have been discussed.

    From among all the tested parameters, the lowest coefficients of friction were obtained in the SS/DLC contacts in water (Fig. 5b); the coefficients of friction in water were lower than the coefficients of friction for the SS/DLC contacts in oil (Fig. 5a). Some possible mechanisms for such low friction that support our result were already proposed in previous studies [30,32–36]. Although it is in agreement, the nanoscale self-assembled monolayer formation studied by molecular dynamics simulations [32] cannot be directly compared to our experimental conditions.

    Many researchers proposed scuffing models based on the breakdown of films such as a hydrodynamic lubrication film [1,2], absorbed additives, oxide films [3], and chemical reaction films [4,5], which prevent direct contacts between the mating solid surfaces. The influence of several factors such as surface conformity, roughness [6,7], wear debris [8,9], and contact temperature [10,11] on the scuffing phenomenon has been discussed because these play important roles in the formation of the films. Even after the breakdown of the films, the scuffing phenomenon does not terminate but proceeds towards the material-failure process of the mating surfaces, eventually resulting in a catastrophic failure.

    When it comes to diesel motors, the operation using a load less than 30% the nominal, can generate an excessive quantity of unburnt fuel, which will go on to produce an increase in pressure in the next compression stroke. This causes a reduction in the lubrication between the cylinder sleeves and the segment rings, resulting therefore in a repetition of the process, greater wear, which may lead to permanent damage [8–10]. When an induction motor is connected to a bus on an electric system, the effects on its start-up are less severe than when connected to a diesel group containing a synchronous generator, as the reactive power from this generator is extremely limited if compared to that of an electric power network.

    Apart from this fact, it has generally been accepted that the constituent that is necessary but most often insufficient to scuffing in which the lubricated system occurs is the breakdown of the EHL or boundary film. The problem of precise identification of scuffing initiation follows from the fact that none of the specific theories (e.g. [5–9]) describes this process in a universal way; most of these theories concern concrete material pair and applying friction conditions. Some kind of synthesis in this field was carried out by Bowman and Stachowiak [10], who listed several factors conducive (especially in synergic occurrence) to scuffing initiation:
