Self-lubrication of Al2O3/TiC/CaF2 ceramic composites in sliding wear tests and in machining processes

Abrasive wear performance of tungsten carbide based self-lubricant cutting tool material

“…Wear rate (10 −5 × mm 3 29.4 N) and wear rate, Z of test materials was computed using the following relation.…”

“…The cutting tool with higher TiB 2 content exhibited lower friction coefficient. Deng et al [3] developed Al 2 O 3 /TiC/CaF 2 composites and evaluated the performance of the sliding wear with the aid of the block on ring test configuration. Material without CaF 2 exhibited significant surface damage and abrasive wear is identified as the dominant wear mechanism.…”

“…However, these materials are not suitable for machining application, where high temperature is involved. Hence CaF 2 is preferred for cutting tool application particularly as a filler in the composite [1][2][3].…”

Microstructure, Wear, and Corrosion Characteristics of TiC-Laser Surface Cladding on Low-Carbon Steel

“…TiC, as one of common ceramics, has many excellent advantages, such as very high melting point and thermal stability, high hardness and excellent wear resistance, low coefficient of friction, good resistance to thermal shock, high electrical and thermal conductivities, and is widely used as the reinforcement in many wear-resistant materials. [16,17] Moreover, the TiC particles have good compatibility with the iron base matrix. [18] Fe-TiC composites have also received increased attention of late due to their high specific strength arising from the low density of TiC and its high hardness and they can be used in high temperature applications.…”

Improvement in tribological properties of atmospheric plasma-sprayed WC–Co coating followed by Cu electrochemical impregnation

“…They have excellent prospects for tribological applications, especially under severe conditions [1]. In a variety of applications requiring high levels of wear resistance, WC-Co is the most common material in this class and has been in use since the 1930s.…”
