“…[1,2] The exceptional wear resistance and microhardness of AISI M2 high-speed steel have garnered widespread recognition. [3] However, the scope of its application within the realm of laser cladding remains largely untapped. This study thus undertakes the utilization of laser cladding to deposit M2 powder onto the surface of A2 mold material, aiming to probe into the mechanical attributes of the resultant coating.…”

AISI A2 tool steel is commonly employed as a material for bending molds. However, its relatively low wear resistance and microhardness significantly impact the precision of formed workpieces. This study aims to address these challenges by applying the laser cladding technique to produce an AISI M2 coating. Sixteen distinct experimental setups were devised using an orthogonal approach. The mechanical performance of the coatings, encompassing microhardness, friction performance, wear resistance, and bond strength, was systematically explored across various process parameters, including overlap rate, laser power, scanning speed, and powder feed rate. A novel algorithm was introduced to comprehensively evaluate the coating's performance. The Grey Relational Analysis (GRA) method was employed to determine the weights associated with different performance responses. In conjunction with the TOPSIS method, this algorithm facilitated comprehensive performance scoring across the 16 experimental groups. Finally, leveraging signalto-noise ratio analysis (SNR) and analysis of variance (ANOVA), the optimal process parameters were identified: an overlap rate (O) of 30%, scanning speed (S) of 3 mm/s, laser power (P) of 800 W, and powder feed rate (F) of 0.9 g/min. Validation experiments conclusively demonstrated that the coating showcased superior comprehensive performance under these rigorously determined process parameters.

“…One way to reduce manufacturing costs is to extend the lifespan of cutting tools [1] by improving their surface properties. [2][3][4][5][6][7][8][9] Several surface treatment techniques can enhance metallic materials with properties such as wear resistance, corrosion resistance, and increased toughness, among others. [10][11][12][13][14][15][16][17][18][19] Plasma nitriding by cage cathodic has been studied in the past decade as a technique that can be used both in the nitriding process and in the deposition of thin films.…”

Plasma nitriding has been extensively used to improve materials’ surface and mechanical properties using conventional plasma techniques. However, this process generally results in a nonuniformity of the properties. In the cathodic cage plasma nitriding (CCPN), the plasma is active only on the surface of the cathodic cage, eliminating inherent defects of conventional plasma nitriding. Herein, a duplex treatment, CCPN and TiN deposition, is used on SINTER30 tool steel for the first time. Vickers microhardness tests, X‐ray diffractometry, Raman scattering spectroscopy, and scratching tests characterize the samples. The results show that TiN post‐coating attains higher surface hardness. All the groups increase their microhardness properties when compared with nontreated substrates. The prior treatment of plasma nitriding assists hardening of the substrate surface. The best condition is obtained when the sample is placed inside the titanium cage and positions directly on the sample port, with simultaneous duplex treatment. When the substrate passes through this simultaneous duplex process, peaks corresponding to Fe3N and TiN are observed at Raman spectra. Suitable TiN layers improve the film adhesion, which is correlated to the system's load‐bearing capacity.
