Sliding Wear Behaviour

For the realization of liquid lubricant free forming processes different approaches are conceivable. The priority program 1676 “Dry forming - Sustainable production through dry machining in metal forming” addresses this issue in the context of metal forming processes. The present study reports results from one subproject of the priority program that employs selective oxidization of tool steel surfaces for the implementation of a dry sheet metal deep drawing process. Within the present study, specimen surfaces of the tool steel (1.2379) were heat-treated to optimize their tribological properties with respect to sliding wear behaviour in contact with drawn sheet metal (DP600+Z). The heat treatment was designed to result in the formation of selective oxide layers that can act as friction reducing separation layers. The heating setup employed an inductive heating under protective gas atmosphere. Selective oxidation was realized by controlling the residual oxygen content. Specifically, the specimens were heated in the near-surface region just above the annealing temperature, thus avoiding the degradation of mechanical properties in the bulk. Evaluation of hardness along cross-sections of each specimen revealed suitable initial temperatures for the inductive heat treatment. Oxide layer systems were analyzed regarding their tribological sliding wear behaviour after selective oxidation, as well as their morphology and chemical composition before and after the sliding wear tests.

Minimum Wear

The NiCr metal is deposited on martensitic stainless steel using atmospheric plasma spray method. To enrich the metallurgical properties of the NiCr metallic coating, a standard heat treatment process is adopted. From the investigation it has been clarified that the voids and porosity developed during the thermal spray has been controlled through the heat treatment. Electron image analysis reflects that the coating has reduced porosity with strong and dense bonding strength. With reference to the surface hardness, the post processed coating yields maximum of 140 Hv compared to as coated (129 Hv) and base metal (115 Hv). Subsequently the sliding wear behaviour of post processed NiCr Coating has a minimum wear 25µm for 5N and 57µm for 15N applied load respectively. Due to the high metallurgical bonding, the coating has sustained the heavy loads and the wear formation is controlled. However, the base metal has adhesive wear mechanism due to high frictional force on sliding friction. Since, it is recommended that the post processed thermal barrier coatings can possess good metallurgical bonding and withstand heavy load causing minimum wear.

Sliding Wear Behaviour

Abstract:Mild steel offers a variety of properties for various applications at lower costs giving the alloy a large application base in industry. However, the increasing complexity and severity of service environments has shifted the focus of many industries to structure modification techniques, like heat treatment, to improve material properties and performance. The focus of this paper was to therefore investigate the effect of heat treatment induced hardness on the sliding wear behaviour of mild steel. The results showed that resistance to dry sliding wear increased with increasing hardness of the mild steel samples. Both abrasive and adhesive wear mechanisms were observed to occur on the samples, however abrasive wear was predominant.
