“…Another factor influencing on the wear process is the condition of the surface layer, where the most significant impact has hardness, which is often associated with high abrasive wear resistance [ 47 , 48 , 49 ]. However it obviously is not only one phenomena resulting on wear resistance, so that it is not uncommon to find results in the literature where an increase in hardness may have no or even detrimental effects on abrasion resistance [ 50 , 51 , 52 ].…”

This article presents the application of the ring-on-ring test to investigate some of the important factors affecting the abrasive and corrosion wear of a face seal used in the sugar industry. The test involves the sliding contact between two steel rings working in different conditions such as mechanic, abrasive, corrosive extortions and its combination. Rings were made of the C45 steel and the surface layers were modified by heat and thermochemical treatment such as normalizing, flame hardening, nitriding and chrome diffusion. Maximum wear of the sample after tests under mechanic, abrasive and corrosion extortion were obtained. For C45 steel without surface modification the biggest wear was obtained for mechanical, abrasive and corrosive extortion and equals 0.0138 g. This value was three times bigger than the result for the mechanical extortion and ten times than for the corrosive conditions. For individual research options the percentage increase or decrease in wear resistance in relation to the normalized surface layer was determined. In the corrosive extortion the highest increase (90%) of wear resistance was recorded for the chrome layer relative to normalizing sample. The main conclusion of the paper is that the wear effect caused by all factors—mechanical, abrasive and corrosive—is not a straight sum of values of wear.

“…This implies the steel’s Mn/C composition ratio lies within the original standards of the austenitic manganese steel. The Hadfield steel consists of a Cr content of 0.3 wt%, which is essential for the yield strength and corrosion resistance of the Hadfield steel [ 48 , 49 ]. The Hadfield steel had a grain size of 300 µm.…”

Electrochemical polarisation tests were carried out on three grades of WC-Co cemented carbides to investigate the corrosive behaviour of the hardmetals and rank them as viable protective liners for chutes and skips in the mining industry. The cobalt binder content and WC particle size varied. The binder content ranged from 6–12 wt%, and the grain size of the WC particles ranged from 0.4–2.3 µm. The performance of the WC-Co hardmetal was compared to three different grades of high chromium white cast irons and Hadfield steel. The cast irons varied in both their chromium content and the morphology of the Cr-rich primary carbides. Potentiodynamic polarisation and linear polarization resistance scans were used to determine the corrosion current density and other electrochemical parameters. The microstructural characteristics of the samples were analysed using Scanning Electron Microscope(SEM) with Energy Dispersive Spectroscopy (EDS), and optical microscopy. The potentiodynamic scans revealed that, although the WC-Co alloys were found to have generally improved corrosion resistance, it was the high-Cr white cast iron (22 wt% Cr) that recorded the lowest corrosion current density and therefore displayed the best resistance against corrosive attack in 1 M H2SO4. The Hadfield steel exhibited the poorest resistance to corrosion and therefore, suffered the most degradation to its exposed surface.

“…Chen et al [32] presented the tensile properties and microstructural behaviour of Hadfield steel by applying different strain rates during tensile test and found that by the addition of N+Cr tensile strength increased considerably. Xiaoyun [33] investigated the mechanical properties and anti-corrosion behaviours of Cr and Mn addition to Fe-Mn-CAl-Cr-N steel have investigated and found that Cr addition increased ultimate tensile strength and yield strength but reduced percentage elongation.…”

The significant demands of steel in industrial applications and automotive and building industries are increasing. Thus, there is a need for the improvement of its mechanical properties by adding suitable alloy elements to them so that they have more strengthweight ratio. The objective of this research is to study the effect of adding various alloys to steel material and their effects on tensile and impact strengths, hardness, and microstructure. The tensile test was conducted on a round bar standard specimens of three kinds of steel having different compositions to investigate their mechanical properties. The results of tensile tests are given in tables, based on their stress-strain curves plotted to facilitate the design engineer to know the strength and accordingly design lightweight structures from this material. After the test, the microstructure of the fracture surface was observed using an inverted microscope. The tensile and impact strengths and hardness of carbon steel, EN 8 steel, and mild steel were evaluated and compared based on the chemical composition and microstructural observation. The experimental result showed that the increasing percentage of carbon and silicon in EN 8 steel increased its ultimate tensile and yielded strengths but reduced the percentage elongation compared to carbon steel. Similarly, less content of manganese with an increased content of nickel enhanced the impact strength of the mild steel but slightly reduced the tensile strength and hardness of mild steel compared to EN 8 steel.
