What according to you should be researched/accessed with respect to WC based solid lubricant tools? What is your view with respect to future research in this area? (For e.g. Tribological study etc..)
Thanks in advance..
May be this paper:
D. Jianxin, W. Ze, L. Yunsong (2014) Design, Fabrication and Properties of Textured Self-Lubricated Tools in Dry Cutting. Materials Science Forum Vols 773-774 (2014) pp 414-419. doi:10.4028/www.scientific.net/MSF.773-774.414
Can help you.
Best regards.
Dear sir,

There are two pathways. One is to use solid lubricant coatings on the cutting tools. Typical solid lubricant coatings are MoS2 and WS2 based (only examples) coating. However, they tend to be soft and less wear-resistant. So they are to be deposited on the cutting tool as a hybrid coating - having a hard phase (like TiN, TiCN, TiAlN etc.) and a solid lubricant based phase (like MoS2, WS2 etc.).

The other pathway is to supply solid lubricant at the machining zone externally during machining. This can be attempted to be achieved by minimum quantity or small quantity cooling lubrication. Some of the researchers have attempted solid lubricant in the aqueous base fluid:

Thanks Soumitra Paul sir for your extensive in depth answer. I will surely go through the articles.
There are four different ways by which the solid lubricants can be explored/have been explored by the researchers in recent past for enhancing the tribological performance during machining. First is to use as solid nano-particles as coatings on the cutting tools may be in the pure from ( individual solid particles) or as hybrid coatings (use of two or more than two solid participles in the coatings). Second in case of uncoated tools these particles can be mixed with base materials for making the tools through powder metallurgy to improve the tribological performance (Like mixing of Graphene and nano-partciles of Graphite can be explored). Third is to use these solid nano particles along with textured tools (to fill the textures of the tools with solid nano particles) to enhance the tool life by reducing the chip tool friction. Fourth is to mix these solid nano particles with the base fluid and to spary these mixture on the cutting zone (rake face/flank face).
Mr Pranjal now for checking the tribological behavior of these solid particles, one must explore the relation between structure of the solid particle (layered structure etc..) and physics behind the tribological behaviour (physical distortion, rolling effect etc... was responsible for enhanced tribological behavior of these solid particles in machining). For start of any study for the use of these solid particles one must analyze the structure of these particles using SEM/TEM... whatever characterization technique it is feasible to check the physical structure.
It is also important to identify that, apart from lubrication whether these solid particles has helped in effective cooling during machining if yes then how (may be when used in base fluid). Thus apart from tribological behavior, rheological properties, chemical inertness and thermal conductivity etc... are also important for these solid particles.
