WEAR PROPERTIES AND MICROSTRUCTURE OF WC–10Co–4Cr POWDER COATING APPLIED TO CULTIVATOR BLADES VIA HVOF

Abstract

Abrasion of cultivator equipment parts working in the soil causes serious losses if necessary precautions are not taken. The cultivator blades used to plow the soil in agricultural production wear out over time. In order to reduce this wear, the hardness and wear resistance of the material should be increased first. In this study, some of the 30MnB5 cultivator blades were heat-treated and some were coated with HVOF technique. The samples were obtained by plowing the soil at 15-cm working depth and 5.4-km[Formula: see text]h[Formula: see text] forward speed in two fields with different soil moisture contents. As a result of the experiments, abrasion losses and surface deformation of the blade material were observed and the effect of soil moisture on wear was also determined. After the treatment of 49.5[Formula: see text]daa (decare) with soil at 9% moisture content, the heat-treated 30MnB5 sample was worn 5.6 g, and the sample coated with WC–10Co–4Cr was worn 3.2[Formula: see text]g. Abrasions at 14% soil moisture were 6.3 g and 3.6[Formula: see text]g, respectively. It was observed that the coated material was less corroded than the heat-treated material. While the results obtained will contribute to the prevention of economic losses, the release of metals into the soil will also be prevented.

Determination of abrasion resistance of Fe28Cr5C1Mn coating applied to 30MnB5 boron alloy cultivator blades via electric arc spray

“…However, they cannot sufficiently increase the performance of high-tech, high-capacity cultivation implements. In particular, in order to extend the economic life of cultivator blades and achieve high productivity, [5][6][7] scientists have investigated different practical techniques such as carburizing, nitriding, carbonitizing, 8,9 and boriding. 10 Scientists have from time to time also used various surface quality improvement techniques such as thermal spray coating, surface hardening, electrodeposition, melting of flux-cored wires and others.…”

Determination of wear resistance of nickel-carbide alloy coating by atmospheric plasma spray technique on 30MnB5 alloy steel used in cultivator blades

“…Additionally, iron carbides in the form of black colonies appear to have an irregular morphology. In a similar study, Singh et al [38] and [4,[24][25][26] observed pearlitic, ferritic, and cementitic phases for steels with the same microstructure. As shown in figure 7, x-ray Diffraction Analysis Confirmed The Presence of cementite and ferrite phases in this material.…”

“…Therefore, a protective coating on the surface can be a practical solution. Thermal spraying is the most common surface technology for applying wear protection coatings [7,[18][19][20][21][22][23][24][25][26], with atmospheric plasma spraying (APS) being the most practical of the thermal spraying techniques [17,27].…”

Comparative studies of the three-body abrasion wear resistance of hardfacing Fe-Cr-C-B-Ti alloy

“…The hardfacing is considered as economical way to improve the performance of components submitted to severe wear conditions, with wide range of applicable filler materials [29,30,31,32]. Among the methods of applying a wear-resistant layer by the method of hardfacing, the following IOP Publishing doi:10.1088/1757-899X/1277/1/012016 2 were most widely used: shielded metal arc or manual metal arc welding (SMAW or MMAW) [33], gas metal arc welding (GMAW), submerged arc welding (SAW), self-shielded flux-cored arc welding (FCAW-S) [34,35,36,37].…”
