“…Kejadian aus yang rendah pada mata pisau TC terlapisi AlCrN disebabkan oleh kekerasan dan suhu oksidasinya yang tinggi, serta koefisien gesekannya yang rendah. Hasil yang sama juga telah dilaporkan pada penelitian sebelumnya (Kumar et al 2014;Chandrashekhar et al 2016). Fenomena ini membuktikan bahan pelapis yang diaplikasikan pada permukaan substrat pisau TC dapat memberikan perlindungan pada mata pisau melalui perbaikan karakteristiknya.…”

The scarcity and high cost of high-quality sawn timber has resulted in the switching of furniture industry to using composite wood such as medium density fiberboard (MDF) as the raw material for its products. One of the factors that affect production costs and product quality in the furniture industry is the quality of the cutting tool used in the cutting operation. The quality of the cutting tool could be improved through the addition of coatings on the surface of cutting tool (surface coating). The purpose of this study was to determine the life time of AlCrN, TiAlN, and TiN coated tungsten carbide (TC) tools in cutting MDF. Cutting operations were performed on a computer numerical control (CNC) router machine at feed per revolution (Frev) of 0,10, 0,15, 0,20, and 0,30 mm/rev. The TC cutting tool life was determined based on its wear and was calculated using the Taylor tool life formula. The results showed that coated TC cutting tool provided a better wear resistance and longer life than uncoated TC cutting tool. The low of Frev set in cutting MDF resulted in a lower wear and longer life of cutting tool. AlCrN coated TC cutting tool provided the best wear resistance and longest life, thus it promising to be developed and used in cutting MDF. Keywords: coated cutting tool, medium density fiberboard, surface coating, tool life, wear

“…Mechanical and tribological results show AlCrN coating possesses high hardness and excellent wear resistance than the TiAlN and AlTiN coatings against boundary lubrication (Özkan et al 2018). Chandrashekhar et al (2016) were deposited AlCrN and TiAlN coating on EN-353 steel, and they observed AlCrN coating has excellent mechanical and wear properties compare to TiAlN coating.…”

The life of metal forming dies, and the efficiency of tooling industries depends on the mechanical and wear properties of tool steel. These properties can be further improved by depositing the ceramic coating on heat-treated tool steel. There are many coating materials available with numerous excellent properties. But problem is how to select the best coating material. Compared to various studies related to material selection problems in the contrasting area of utilization, remarkably, few research work is done in tooling industries. In the present work, we have identified eight coating materials (alternatives) and nine evaluation criteria under the consultation of an expert in the tooling application and tribological field. To deal with this coating material selection problem, an integrated fuzzy-MADM method is proposed comprising BWM and fuzzy-MARCOS. This integrated fuzzy-MADM method is used to evaluate the alternative, and the obtained results are scrutinized under extensive use of sensitivity analysis. In the first phase of analysis, seven scenarios of criteria weight change are used, which is derived by the BWM method; dynamic matrices are used in the second phase of analysis. In the third and fourth phases, obtained ranks are compared with those obtained by different weight calculation methods and ranking methods, respectively. All the phases have similar results, i.e., AlCrN/TiAlN coating (alternative Cm5) is the best coating material. What is more, the proposed method has been used to solve the published results of coating material selection. To evaluate its reliability and robustness, a four phases comparative sensitivity analysis was performed.

This paper reports the effect of coating thickness on adhesive properties, and residual stresses by the electric discharge coating (EDC) process on Mg alloy with copper (Cu) nickel (Ni) powder metallurgical (P/M) electrodes. The composite coating layer thickness was measured by optical microscope and it ranges from 10.2 to 102.4 µm. The coating layer was characterized by a Field emission scanning microscope (FESEM) and Energy-dispersive spectroscopy (EDS). X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) analyses were made to identify the chemical composition and functional group. Residual stresses were evaluated by an ETA diffractometer and it revealed that compressive residual stress increases with a range of −458 ± 118 MPa to −1078 ± 125 MPa and tensile residual stresses decrease from 656 ± 113 MPa to 27 ± 11 MPa. The critical load is measured by scratch test. The result shows the adhesive strength of the coated surface was improved with an increase in layer thickness.
