Diamond burnishing is an effective finishing process to enhance the surface quality and production rate of machined components. The purpose of this investigation is to select the optimal process parameters, including the spindle speed (S), feed rate (f), and burnishing depth (D) of the hybrid cooling-lubrication system-based diamond burnishing process for decreasing the average roughness (AR) and improving Vickers hardness (VH).

In this thesis, the rolling contact wear of 52100 bearing steel and Over-aged Magnesia-Partially-Stabilised Zirconia (OA-Mg-PSZ) ceramic are examined using a newly developed rolling contact wear test rig. The new wear test rig simulates the system geometry of an un-lubricated hybrid (ceramic and steel) ball bearing. The new wear test rig is versatile in that it allows low cost samples to be utilised resulting in a larger number of samples that can be tested.

This paper focused on evaluating those properties based on the data of acoustic emission and electrical contact voltage signal. Frictional experiments based on scratch test and pin-on-flat model were conducted with CrN coating, lubricant samples to obtain some experimental data, including contact pressure, friction force, friction coefficient, acoustic emission, and contact voltage.

Lubricants have been applied in numerous industrial fields, as they help reduce friction and heat generated when operating machines and also protect metallic parts in corrosive environments. In some applications, especially in marine, these greases need to be biodegradable, or they get accumulated and can be harmful to aquatic life.

Polysaccharides strongly affect the sensorial properties of foods, which is partly related to the lubrication they provide. We investigated the lubrication performance of polysaccharides with different characteristics (i.e. molecular weight, conformation, stiffness, and charge density) to identify the most relevant structural features related to lubrication ability.

In a hydrostatic spindle of machine tools, the bearing structure parameters, lubrication characteristics and working conditions are factors affecting the spindle stiffness and the machining quality. Besides some known geometrical parameters and oil viscosity, other factors such as lubricant pressure and loading capacity need to be determined to find a feasible working condition for a machine tool.
