“…The overlay coating technology, so called a hardfacing technology, can deposit the super-alloy with excellent wear properties at the elevated temperature on the substrate [3][4][5]. In addition, the metallurgical bonding is created in the vicinity of the joined region between the overlay coated layer and the substrate [3][4][5]. Hence, several engineers related to the development of hot-working tools have paid attention to the application of the overlay coating to the hot-working tools [3][4][5].…”

Hence, several engineers related to the development of hot-working tools have paid attention to the application of the overlay coating to the hot-working tools [3][4][5]. Since the metal threedimensional (3D) printing technology has been developed, the interest in the overlay coating technology has greatly increased to extend the service life of hot-working tools through the reduction of an excessive wear of the tool surface [3,6,7].…”

Abstract.Interests in an overlay coating technology, so called hardfacing technology, have steadily increased to improve the service life of hot-working tools through the reduction of the wear of tool surfaces. Characteristics of the overlay coated layer are dependent on geometrical parameters and material properties of sub-layers. The aims of the paper is to examine the effects of geometrical parameters of the overlay coated layer on thermal stress-strain distributions of Co-based super-alloy deposited layer on hot-working tool steel using finite element analysis (FEA). The overlay coated layer is designed as two sub-layers including the wear resistance layer with Co-based super-alloy and the thermal stress control layer (TSCL). The material of the TSCL is composed of 50 % of Co-based super-alloy and 50 % of hot-working tool steel. The protruded height and the inclined angle are chosen as geometrical parameters. The influence of the protruded height and the inclined angle on thermal stress-strain distributions in the vicinity of the overlay coated layer and the strain deviation in joined regions is quantitatively investigated. From the results of the investigation, an appropriate design methodology of the overlay coated layer is discussed.

“…Besides the thermal fatigue, wear appears as the frequent cause of damages to this type of tools. The wear of forging dies, due to abrasion and adhesion, was the subject of research in [4], where the hard facing was applied as a method for recovery of the sustained damages. To extend the service life of the forging dies, their wear was analysed numerically in [5] during the final phase of forging.…”

Subject reviewThe forging dies are parts, which are operating at elevated temperatures, while simultaneously subjected to variable loads that can be compressive -even impact and shear. Impact of the hard facing technology is very strong since varying of the hard facing parameters directly affects the output characteristics of the hard faced layers. The criterion for estimating that impact was based on results of performed tribological investigations. The tribological parameters that were monitored were the friction coefficient, the wear scar/trace width and the wear area of the hard faced layers, with the two different types of lubricants. Hard facing technology implied selection of the welding process, filler metals, preheating temperatures and other parameters of the hard facing process. The influence of the proposed hard facing technology was determined by monitoring hardness, microstructure and wear resistance of the executed joints after the hard facing and after tempering. The objective of this work was to establish the correlation between the selected hard facing technology, filler metals and applied heat treatment on mechanical and tribological characteristics of the executed hard faced layers. Keywords: forging dies; friction coefficient; hard facing; hardness; microstructure; wear resistance Utjecaj tehnologije navarivanja i dodatnog materijala na tribološke karakteristike navarenih kovačkih alataPregledni članak Kovački alati su dijelovi, koji rade na povišenim temperaturama, dok su istodobno izloženi promjenljivim opterećenjima, koja mogu biti tlačna -čak i udarna i smična. Utjecaj tehnologije navarivanja je vrlo jak, pošto se variranjem njegovih parametara direktno utječe na izlazne karakteristike navarenih slojeva. Kriterij za procjenu tog utjecaja bio je utemeljen na rezultatima obavljenih triboloških ispitivanja. Praćeni tribološki parametri bili su faktor trenja, širina traga (brazgotine) habanja kao i površina habanja navarenih slojeva, uz uporabu dva tipa maziva. Tehnologija navarivanja je podrazumijevala selekciju procesa zavarivanja, dodatnih materijala, temperature predgrijavanja i ostalih parametara procesa navarivanja. Utjecaj predložene tehnologije navarivanja je određivan praćenjem tvrdoće, mikrostrukture i otpornosti na habanje izvedenih spojeva, nakon navarivanja i nakon otpuštanja. Cilj ovog rada bio je uspostavljanje korelacija izabrane tehnologije navarivanja, dodatnih materijala i primijenjene toplinske obrade s mehaničkim i tribološkim karakteristikama izvedenih navarenih slojeva.
