Wear Behavior and Wear Worn Surface Analysis on Hardox Steel

Abstract

High quality and behavior of steel is playing an essential role in metal and manufacturing industries. Hardox steel has exceptional properties includes high wear resistant and hardness. The wear behavior of hardox 400 steel was evaluated through pin on disc tribometer using different input constraints such as load, sliding velocity and disc speed. The wear worn surface was investigated through atomic force microscopy. The wear rate of the hardox steel was calculated with different load conditions. The wear factors and wear rate were optimized by taguchi method. Variance analysis was provided the contribution of each factor on mass loss.

Research of Resistance of Selected Materials to Abrasive Wear to Increase the Ploughshare Lifetime

“…The sample was etched with Cor etchant (120 mL CH 3 COOH, 20 mL HCl, 3 g picric acid, 144 mL CH 3 OH). The finegrained structure corresponds to the state after heat treatment-hardening and tempering, which is stated and declared by the manufacturer in his technical sheet [27].…”

“…It provides good abrasion resistance and thus a longer lifetime. It has better wear resistance [27], higher load capacity, and a longer lifetime compared to ordinary steel with the same hardness. It is used in various components and constructions that are subject to wear [9,27,28].…”

“…It has better wear resistance [27], higher load capacity, and a longer lifetime compared to ordinary steel with the same hardness. It is used in various components and constructions that are subject to wear [9,27,28]. The chemical composition of HARDOX 450 material is shown in Table 3.…”

“…Table 3. Chemical composition of S355J2G3 [24], 37MnSi5 [25], HARDOX 450 [27] steels and OK 84.58 [29] and UTP 690 [31] hardfacing materials according to the datasheets. All samples, both standard (S355J2G3 and 37MnSi5) and reference ones (HARDOX, OK 84.58 and UTP 690), were prepared according to the GOST 23.208-79 standard by abrasive water jet cutting technology (AWJM), machined by milling and ground by a magnetic surface grinder for obtaining dimensions 30 mm × 30 mm × 10 mm and surface roughness Ra = 0.4 µm (Figure 6).…”
