Investigation of the WEDM Parameters’ Influence on the Recast Layer Thickness of Spark Plasma Sintered SiC-TiB2-TiC Ceramic

“…SiC-TiB 2 -TiC is a ceramic composite that has attracted considerable attention because it shows very good mechanical properties, for instance, high tensile strength, chemical resistance, and creep, and good corrosion resistance and electroconductivity [6][7][8]. The set of these properties in a single material makes it promising for its application in different areas such as coatings, drawing or extrusion, bearing parts, valve seats, seal rings, various hightemperature engine parts, etc.…”

“…Furthermore, the addition of TiB 2 to the SiC-TiC system can influence the cutting tool wear resistance and increase it because TiB 2 , under high cutting temperatures, transforms into TiO 2 and B 2 O 3 , which can act as lubricants and crack healers [5,15,16]. Different sintering techniques have been used for the consolidation of this system, for instance, Hot Pressing [17][18][19][20], Reactive Hot Pressing [21][22][23], Arc melting [7,24], Presureless Sintering [25], and Self-propagating high-temperature synthesis [6]. All these works have shown that the sintering process of the SiC-TiB2-TiC system using traditional methods requires higher temperatures and/or pressures with long dwell times because of the low self-diffusion coefficients, high melting temperatures, and the covalent bonds of the system components [26][27][28][29][30].…”
