Assessment of the impacts of bio-dielectrics on the textural features and recast-layers of EDM-surfaces Mater. Manuf. Process. (IF 3.046) Pub Date : 2020-10-15 Shirsendu Das; Swarup Paul; Biswanath Doloi
ABSTRACT The alternative dielectrics like vegetable oils, emulsions, and different organic solutions have captured the emerging research attentions, and few pieces of literature also discussed about their potentiality to replace conventional kerosene. However, observations of the existing literatures are limited up to the assessment of the primary responses like material removal rate (MRR), surface

Feasibility of steel powder deposition on composites through cold spray Mater. Manuf. Process. (IF 3.046) Pub Date : 2020-10-12 Roberta Della Gatta; Antonio Viscusi; Alessia Serena Perna; Antonio Caraviello; Antonello Astarita
ABSTRACT The deposition of steel powders on glass fiber reinforced polymer (GFRP) with the Cold Spray technique is investigated. Metallization of composite materials is still challenging when high-strength and dense powders, such as steel, are used due to excessive erosion of the polymer or disruption of the fibers during the deposition. To overcome these issues, low-pressure cold spray equipment has

Effect of electro-codeposition parameters on particle incorporation in Ni-CrAlY(Ta) coatings Mater. Manuf. Process. (IF 3.046) Pub Date : 2020-10-12 J.C. Witman; Y. Zhang
ABSTRACT Electrolytic codeposition is a promising alternative low-cost process for fabricating MCrAlY coatings. In this process, CrAlY particles are codeposited with the (Ni,Co) to form an (Ni,Co)-CrAlY composite coating, which is subsequently heat treated at elevated temperatures to be transformed to the MCrAlY coating containing phases of β-NiAl, γ-(Ni,Co), etc. A permeable rotating barrel was utilized

Developed diamond wire sawing technique with high slicing ability for multicrystalline silicon wafers Mater. Manuf. Process. (IF 3.046) Pub Date : 2020-08-13 Ting-Chun Wang; Tsung-Han Yeh; Shao-Yu Chu; Hsin-Ying Lee; Ching-Ting Lee
ABSTRACT In this work, various reciprocating cycle times of 80, 160, 240, and 320 sec in the diamond wire sawing (DWS) process were adjusted to improve the slicing ability in solar industry. During the same slicing time, the long reciprocating cycle time had less velocity inverse points in comparison with the short reciprocating cycle time. Consequently, the total friction force of the slicing wires

Reverse EDM process for pattern generation using powder metallurgical green compact tool Mater. Manuf. Process. (IF 3.046) Pub Date : 2020-08-13 Rashed Mustafa Mazarbhuiya; Maneswar Rahang
ABSTRACT This work has described about the generation of complex shaped pattern using reverse electro discharge machining process. Powder metallurgical green compact tool has been used to generate a predefined pattern by depositing its constituent materials. A predefined star shaped pattern has been generated on the aluminum 6061 work surface. The pattern has been created by adjusting the process factors
