This study aims to explore the wear performance of maraging 18Ni-300 steel, fabricated via laser powder bed fusion (LPBF). The building direction dependence of wear resistance was investigated with various wear loads and in terms of ball-on-disk wear tests. The effect of direct aging heat treatment, i.e. aging without solution heat treatment, on the wear performance was investigated by comparing the wear rates of directly aged samples, followed by solution heat treatment. The effect of counterpart material on the wear performance of the maraging steel was studied using two counterpart materials of bearing steel and ZrO2 balls. When the bearing steel ball was used as the counterpart material, both the as-built and heat-treated maraging steel produced by the LPBF showed pronounced building direction dependence on their wear performance when the applied wear load was sufficiently high. However, when the ZrO2 ball was used as the counterpart material, isotropic wear resistance was reported. The maraging steel produced by the LPBF demonstrated excellent wear resistance, particularly when it was aging heat-treated and the counterpart material was ZrO2. The directly aged sample showed wear performance almost the same as the sample solution heat-treated and then aged, indicating that direct aging can be used as an alternative post heat treatment for tribological applications of the maraging steels produced by LPBF.

“…However, in addition to the questionings on the concepts of ASTM G98 standard [2,[4][5][6][7][8], literature [4,9] data also indicates that the preparation of these tests must be careful in order to provide good alignment between the contacting surfaces, even if some of the alternatives to the original standard are selected. The better performance of the coated tools may be attributed to their ability to minimize, or postpone, the occurrence of galling; an ability that was verified as an absence of particles adhered to the tool surface and the absence of additional peaks and valleys in the roughness profile.…”

“…One important reference regarding these tests is the ASTM G98 method [3], according to which a threshold pressure for galling is calculated based on the visual inspection of the presence of galling at the surfaces of a button and/or a block that were pressed against and manually rotated with respect to each other at increasing loads. Other questionings on the ASTM G98 test method include the non consideration of the statistical nature of galling [4,5]; the absence of constant speed during manual rotation [6] and even cost issues associated with the necessity of a large number of specimens or the availability of an equipment capable of applying large normal loads [7]. These changes intend to overcome some of the method limitations, such as the heterogeneity of contact pressure distribution [4] or the fact that the velocity is zero at the centre of the rotating button [2,4].…”

“…Agricultural operations, inherently prone to friction and wear, have been integral to human activities since ancient times (Mehulic et al, 2005) [18] . Wear, defined as the progressive loss of material due to relative motion between a solid surface and contacting substances, poses a particular threat in agricultural machinery (Gurumoorthy et al, 2007) [8] . Abrasive wear, characterized by the detachment of material from surfaces during relative motion, especially caused by the sliding of hard particles between surfaces, is particularly destructive (Chattopadhyay, 2001) [6] .…”

Wear analysis in the field is a time-consuming and expensive process. Consequently, there arose a necessity to devise a wear testing machine. Unfortunately, abrasive wear testing machines, as developed in advanced countries, are not readily accessible in India. This scarcity makes the investigation of wearrelated issues at laboratory levels a challenging task in the country. The primary aim of this study was to create and assess a wear testing machine in the laboratory setting. The machine comprises a circular soil bin, support frame, power transmission system, working unit, and arm subassemblies. To evaluate the Equipment, rotavator blades were utilized in soils containing 99% sand. L-shaped blades, constructed from EN8 steel material, were affixed to the flange, and their speed was varied between 180 and 200 rpm. The experiment involved operating at a depth of 14 cm and a speed of 0.97 m/s in sandy soil with a moisture content of 8 to 10 percent. Wear tests were conducted under controlled indoor conditions within the circular soil bin for a continuous period of 100 hours. Gravimetric and dimensional measurements of the rotavator blades were recorded at 20-hour intervals in the circular soil bin. The results revealed a consistent increase in wear loss at each time interval at the chosen depth and speed of operation. The blades exhibited wear along their thickness, with the maximum wear observed at the tip of the blades.
