“…There are a number of ways to mitigate problems connected with abrasive and other types of severe wear. Arc weld surfacing [ 8 , 9 , 10 , 11 ] is an effective method to reduce wear losses. Wear resistant materials may be also used to produce the entire working unit [ 12 , 13 , 14 , 15 ].…”

The purpose of the research was to obtain an arc welded joint of a preliminary quenched high-carbon wear resistant steel without losing the structure that is previously obtained by heat treatment. 120Mn3Si2 steel was chosen for experiments due to its good resistance to mechanical wear. The fast cooling of welding joints in water was carried out right after welding. The major conclusion is that the soft austenitic layer appears in the vicinity of the fusion line as a result of the fast cooling of the welding joint. The microstructure of the heat affected zone of quenched 120Mn3Si2 steel after welding with rapid cooling in water consists of several subzones. The first one is a purely austenitic subzone, followed by austenite + martensite microstructure, and finally, an almost fully martensitic subzone. The rest of the heat affected zone is tempered material that is heated during welding below A1 critical temperature. ISO 4136 tensile tests were carried out for the welded joints of 120Mn3Si2 steel and 09Mn2Si low carbon steel (ASTM A516, DIN13Mn6 equivalent) after welding with fast cooling in water. The tests showed that welded joints are stronger than the quenched 120Mn3Si2 steel itself. The results of work can be used in industries where the severe mechanical wear of machine parts is a challenge.

“…Cracks themselves do not significantly affect particle wear resistance, but can initiate fracture under static or dynamic stress. An unsuitable particle shape can cause the matrix to peel off at high loads [Choteborsky 2009] [Jahaveri 2018]. When welding by the TIG method, cracks in the bilayer cladding occurred in low to negligible amounts, as well as their size.…”

“…• the process of injecting the abrasive into the surface, where hardness is the decisive factor; • surface disruption process, where interatomic bonds and the strength of the bond between the structural components at the grain boundaries play a decisive role. Typical situations that occur during abrasive wear can be divided into: [Choteborsky 2009] Ideally, micro-scoring, the passage of a single abrasive particle does not result in any separation of material from the surface. The material is continuously moved to the sides, forming peaks adjacent to the already formed groove (Figure 3a).…”

There is not so much research on the issue of the wear of forestry tools as on tools used in agriculture, mining or construction. However, in a heterogeneous environment, they are subject to abrasive and shock loads. The large number (48 pieces) of tools used at the same time, based on base machine adapters, their rapid wear and the high price of a new tool (approx. 70 Eur), is the reason why it is necessary to deal with this issue. One solution is to apply hardening materials to exposed parts of the tools. These could prevent rapid decommissioning due to the loss of functionality of the tool due to their structure, more resistant to adverse working environments. Methods of applying such a deposit are different. From classical welding methods for example TIG method, up to unconventional, where also plasma welding belongs. The aim of this paper is to present partial results of laboratory experiments of plasma welding and TIG welding with HR MAG welding wire on the tool base material, 16MnCr5 steel. Specifically, the hardness as well as the hardness of the hard-facing material to abrasive wear by the GOST method were examined. Subsequent evaluation of the surface after this test as well as the microstructure itself can give us information on the suitability of the selected material for practical application in forestry.

“…Based on comparison of all results from respective tests it can be observed that the B1 deposit is based on the structure analysis, hardness, adhesive wear, mechanical properties, rolling fatigue and residual stress the best suited clad layer. Based on the performed experimental work, in order to assess the suitability of the clad surfacing layers it is necessary to consider not only the mechanical properties of clad layers, but mainly the mutual relation between them, while considering also the tribological properties of clad layers for specific conditions of their wear in operation [37][38][39][40][41].…”

The paper presents the results of the research aimed at possibilities of renovation of functional surfaces of back-up rolls that are part of the hot strip rolling mill operating line using new types of additive materials. Experimentally, four melts of alloyed steel were produced in laboratory conditions from which four types of filler materials in the form of wires were made. They were made by pulling through dies to a diameter of 2.4 mm. The renovation of functional surfaces was performed on the batch of rolls with the outer diameter of 1000 mm and length 3000 mm. Cladding technology submerged arc welding (SAW) was applied for cladding of four spirals with 40 mm oscillation onto the base material of the 31CrMoV9 (EN 10085) sub-roll. The base flux marked WLDC 17-AWS A5.17-89 EM13K with basicity index 3 was used for cladding. The four-layer weld deposition was made to eliminate the effect of mixing the surfacing layers with the base material. The refurbished rolls were annealed after welding. Surface quality was assessed by visual inspection (VT) according to EN ISO 17637. The presence of internal errors was determined by ultrasound control (UT) in accordance with EN ISO 11666 and EN ISO 17640. The quality of the clad layers was analysed on metallographic sections using light microscopy. The microhardness of the individual clad layers was evaluated according to Vickers according to EN ISO 9015-2. Based on realized experiments it can be stated that the selected cladding parameter was suitable, and the overlay layers showed no surface or internal defects. Mechanical and tribological tests were carried out, but they showed significant influence of chemical composition of additive materials on mechanical properties, or wear resistance of the layers.
