iTSSe TSS ADVANCED MATERIALS & PROCESSES | APRIL 2025 41 iTSSe TSS JTST HIGHLIGHTS AND TSS NEWS SEEKING NOMINATIONS FOR THERMAL SPRAY HALL OF FAME The Thermal Spray Hall of Fame, established in 1993 by the Thermal Spray Society of ASM Inter- national, recognizes and honors outstanding leaders who have made significant contributions to the science, technology, practice, education, management, and advancement of thermal spray. For a copy of the rules, nomination form, and list of previous recipients, visit tss.asminternational.org or contact maryanne. jerson@asminternational.org. Nominations are due September 30. 10 Fig. 3 — Deformation in a DED produced sample from finite element analysis procedure. MECHANICAL PROPERTIES OF COBALT CHROMIUM ALLOY MANUFACTURED BY DIRECT ENERGY DEPOSITION TECHNOLOGY David Smith, Paula Pickett, Theresa Grabowski, Joncy Thorpe, and Fardad Azarmi Cobalt chromium (CoCr), a well-known biocompatible material, is additively manufactured using direct energy deposition (DED) technology in this study. This work investigates some important mechanical characteristics of the additively manufactured CoCr using two different numerical simulation methods in addition to mechanical tests and experiments.

MICROSTRUCTURE FORMATION AND OXIDATION RESISTANCE OF LASER-CLADDING Al3.63Co10.58Cr13.41Fe51.28Mo12.15Ni8.95 COATING Ning Liu, Pei Zhao, Pengjie Zhou, Qichen Zhou, and Xiaoli Wang In this work, Al9.9Co18.18Cr18.18Fe18.18Mo18.18Ni18.18 (at.%) high-entropy alloy was laser cladded on the surface of H13 steel to extend the operating temperature range. Due to the dilution of substrate, coating with a composition of Al3.63Co10.58Cr13.41Fe51.28Mo12.15Ni8.95 (at.%) was achieved, Fig. 5 — Schematic diagram of plasma spray melting system composition. PROCESS OPTIMIZATION OF Ni60A COATING PREPARATION BY PLASMA SPRAYINGCLADDING TECHNIQUE Ming Liu, Qi-qing Peng, Yan-fei Huang, Guo-zheng Ma, Xue-wei Zhu, Zhong-yu Piao, Hai-dou Wang, and Xuanping Luo Ni60A spraying-cladding coatings were innovatively prepared on the surface of the Q235 steel substrate by plasma spraying-cladding technique. Ni60A powder with a particle size of 30 μm was further selected as the optimum spraying-cladding powder based on preliminary numerical simulation. (Fig. 5) which was a multi-phase system composed of FCC + BCC + σ + μ. (Fig. 4)
