“…In equation, η is the response variable, β 0 is the regression constant, β i and β j are the coefficients of regression, X i,j is actual values of independent variables, and k is the numeric of parameter. Mathematical models depending on the tool grade (T) feed (f) and cutting speed (Vc) for resultant force, surface roughness, and cutting power are given in equations (6)(7)(8).…”

The coating performance for indexable inserts is very important for the main machinability indicators such as energy consumption, cutting force, and surface quality, especially in milling operations. The present study intend to the comprehensive analysis of machining conditions for above mentioned machinability indicators that can be considered most important for sustainability in hard milling of a worn machine part. First, the worn zone of the shearing blade made of X40CrMoV5-1 hot work tool steel was filled with electric arc welding. Then, hard milling experiments were carried out to analyze the performance of different coated carbide inserts in the machining of the hardfacing welded part. Experiments were performed by applying L18 experimental design for invariable cutting depth, three different cutting speed, and feed rate with PVD-AlTiCrN and CVD-TiCN/Al2O3/TiN coated inserts. Machining parameters for the responses namely the resultant force (Fr), surface roughness (Ra), and cutting power (Pc) were simultaneously optimized via applying Taguchi-based grey relationship analysis. Finally, predictive models for the responses were developed by RSM. The results obtained by both coatings shown that the Fr and Ra are mainly influenced by the feed rate, while cutting speed is the parameter that most influenced the Pc. The optimum results with regards to the responses were obtained with the PVD-AlTiCrN coated tool. In the current study, the developed quadratic models and probability graphs indicated that the responses were highly predictable.

“…Hardfacing coating layer is a strong bond with substrate metal and this technique provides protection against corrosion with a maximum thickness of 10 mm [50][51][52] Hardfacing technique was used for enhancing excavator bucket teeth, tillage machines and mining tools against abrasive wear. Hardfacing layer thickness ranges from 2 mm to 3 mm with many passes [53]. [54] applied hard alloy coatings on the working parts of agricultural machinery as hard surface against soil abrasion wear against working parts and these coating layers reduced the wear rate and mention that this method is very effective for agricultural machinery.…”

GRICULTURAL production is a world spearhead to face hungry crisis and the main part of this facing is agricultural machinery. Agricultural machinery exposed to failure due to wear and corrosion. This leads to a decreasing lifetime of working parts of agricultural machinery. Agricultural machinery contain seedbed preparation machinery, planting machinery, service and protection machinery, harvesting machinery and post-harvest machinery all types of agricultural machinery deals with different soil condition (soil moistures and soil types), plants (different stem diameter, cutting heights and plants moisture), and agricultural chemical (pesticides and chemical fertilizer). There are many studies searching the optimum method to increase the wear resistance of working parts of agricultural machinery. These methods contain the improvement the new material, hardfacing allying, surface coating, and nanocomposite coating. Nanocomposite coating is a new trend to promote surface properties of the different metal used in manufacturing agricultural machinery. This new trend use nanoparticles as reinforcement in the metal matrix and incorporation process lead to super hardness coating with low corrosion rate and low wear rate compared to conventional surface coating materials.

Purpose The purpose of this study is to show which filler metal is the best for hard facing. Because the quality of the surface layer has a great influence on the working life of parts, the purpose was to extend the working life of parts exposed to intensive wear. The tested hard-faced models were made of low carbon steel to save the expensive base metal and to analyze the possibilities of extending the service life of existing structural parts. Design/methodology/approach Samples were prepared from plates hard faced with various filler metals. Samples were then subjected to experimental testing – testing of tribological properties and hardness and microstructure. Testing was done in conditions similar to real ones – with a sliding speed of 0.25, 0.5 and 1 m/s and with a load of 50, 75 and 100 N and in most rigorous dry conditions. Research was done by using a combination of experimental and theoretical approaches. Findings The paper shows the results of the experimental testing of four different filler metals aimed for hard facing of parts exposed to highly intensive wear. Results shown that CrWC 600 alloy is the most favorable filler metal for hard facing of parts such as those of construction mechanization and those subjected to intensive abrasive wear at stone mines. Practical implications All obtained results are real and fully applicable, as there is a huge industrial need for these types of technologies. With the application of these technologies, beside money savings, the working life of parts can be significantly extended. Originality/value The research presented in this paper was conducted because of the lack of results from this area in Serbia and because of the necessity for application of obtained results in companies for road maintenance and stone excavation in the region of Šumadija, Serbia.
