Diffusion treatments such as chromising and aluminising of high carbon steel results in the formation of Cr and Al rich layers on the surface. These layers will be responsible for formation of protective Cr2O3 and Al2O3 scale on exposure to corrosive environment. In view of extensive application of 316 Stainless Steel in biomedical engineering, present work is undertaken to examine the influence of diffusion treatment of high carbon steel on the reciprocating wear in Hank’s solution and to compare the same behavior with that of 316 SS. In order to achieve the above mentioned objectives, the wear rates of 316 SS, 304 SS, high carbon steel in aluminised and chromised condition have been evaluated. Though the general characteristics of the wear behavior, such as higher wear rate at higher load and at higher reciprocating speed, for all the materials are similar, aluminised and chromised high carbon steel exhibited best wear resistance especially at high and intermediate load. In simulated body fluid condition, 316 SS exhibited two different material removal mechanisms. In the first case, which is observed at higher load, material loss is by nucleation and propagation of crack. In the second mechanism which is prevalent at low and intermediate load, wear takes place by deterioration of composite layer formed on the surface by mixing the corrosion product and the substrate. Consequently it is noted that wear rate decreases with increase of hardness at higher load. At intermediate and at low load wear rate is less dependent of hardness.

High carbon steel (AISI 1065) and stainless steel (AISI 304) are high strength materials that are mostly used as wear resistance materials because of there high hardness and toughness. These two materials are widely used for applications in which high strength, hardness and wear resistance are required, these requirement are fund in cutting tools, springs and surgical instruments. Nevertheless, the presence of notch in these materials do affect their service life. This paper reports on the characteristics of notched high carbon steel and stainless steel materials investigated under tensile, torsion and impact loads. The behaviour of the materials were examined under different notch parameters of angle 30°, 45° and 60° and notch base radius of 0.5 mm and 1.0 mm. The tensile, torsion and impact test samples were prepared according to ASTM E8M, ASTM F383-15 and ASTM E23-16b  respectively. Examination on the tensile and torsion tests were carried out on Testometric Universal Testing Machine (TUTM), while Avery-Denison Izod impact testing machine was used for impact test. The results obtained for the two materials showed that there is increase in absorption energy and resistance to twisting failure as notch tip radius and notch angle increase.

Helical compression spring plays a vital role in vehicle application as it improves ride index, sustains the vehicle against extreme degrees of vibration and stress induced on the suspension system as a result of uneven road. Depending on the extent of load acting on the suspension system, material selection, design considerations and manufacturing processes, longevity and performance of the spring may be sustained, otherwise the spring may fail prematurely under severe loading condition. In this study, compression spring was designed using high carbon steel, stainless steel and chrome vanadium steel and the designed spring models were simulated for maximum Von-mises stress, maximum resultant displacement and resultant strain. Curb weight of the vehicle was considered in the analysis which involves the weight of the car with all fluids and components but without the driver, passengers, and cargo. At the end of the simulation, the three materials remained within the limit of their elasticity without any significant sign of failure under the applied load of 3888N. However, the difference between Von-mises stress obtained for Chrome vanadium and its yield strength was the highest (653MPa) followed by stainless steel (235MPa) before high carbon steel (109MPa). This implies that at increasing loading conditions, high carbon steel will be the first material to fail during operation, whereas, stainless steel and chrome vanadium may exhibit sustained level of longevity before failure as a result of the high chromium content and other alloying elements that gives them a better quality but at relatively high cost compared to high carbon steel which can satisfactorily undergo its service condition at relatively low cost.
