Aluminum Silicon

This study is concerned with the influence of four metallic reinforcements on aluminum-silicon (AlSi) composites, with respect to wear behavior. AlSi-Ti; AlSi-Ti6Al4V; AlSi-1.4301 stainless steel and AlSi-Ni particulate reinforced composites were produced by a hot-pressing route. Microstructural characterization showed a uniform distribution of the reinforcing particles in the AlSi matrix. Reciprocating pin-on-plate wear tests were performed for AlSi and AlSi-based composites against gray cast iron plates. In order to compare the effect of different metallic particulates on the AlSi-based composites/gray cast iron tribopair wear performance, besides the pin, the counterface was also analyzed. The particle/matrix interface is analyzed in order to understand its influence on the tribopair behavior and on the controlling wear mechanisms. It was shown that the better compromise between both sliding surfaces performance was attained by AlSi-Ni/gray cast iron tribopair.

Coherent Interfaces

Bimetallic castings are widely employed as working elements in winning machines which work in conditions of intensive friction wear. The main features of wear are: dynamic percussive loads, intensive abrasive wear caused by erosion and corrosion. Three cylindrical rods cavities of the same dimensions of φ 20x200 mm were made in sand mould. Different amount of liquid iron alloy with carbon equivalent of 4.14, Mn of 0.58 and Cu of 0.17 wt% was poured into the three rod cylindrical cavities over the solid 304 stainless steels cylindrical desks inserts. Good coherent interfaces for all liquid/Solid volumes (16 to 24) are produced and multi-layers interfacial microstructure bimetal are produced. Increasing the liquid/solid volumes from 16 to 24 increases the thickness of transient layer from 52 to 89 μm and decreases the amount of ledeburite in the structure of solidified gray cast iron.

Lubricated Sliding

This research investigates the tribological behavior of gray cast iron against EN31 steel under lubricated conditions. The most typical lubricated sliding phenomena are the reduction of wear on both the sliding surfaces and any one of the critical surfaces. Static and hydrodynamic wear can be reduced based on fluid properties or the accessibility of fluid between the surfaces. The oil’s viscosity or content of the hydrocarbon and additives present in the oil plays a major role in controlling the wear of reciprocating surfaces. Therefore, this research work focused on metal-to-metal contact wear under the influence of lubricating oil (40 pride oil). The Taguchi method was used to select the sliding parameter combinations. Lubricated sliding resulted in a relatively reduced order of friction coefficient, attributable to better load distribution due to the formation of the lubricant film.
