Estimating the term…
A carrier-free pulverulent metalworking lubricant composition. In one preferred form, the composition contains at least two lubricant components one of which comprises a resin having a highly polar functional group the composition being formed by a method comprising the steps of: (a) forming a dry mixture of said particulate lubricant components, and (b) agglomerating said admixture to form agglomerated particles. The application of the composition as a metal working lubricant significantly reduces smoke and oily waste generation in hot forging operations by eliminating the use of oils or volatile organic compounds as carriers, while providing acceptable performance, cleanability, and sprayability.
A carrier-free pulverulent lubricant composition comprising at least two particulate lubricant components, and at least one of said components being graphite, the particles of said composition consisting essentially of particulate lubricant components which have become fused together in a heterogeneous mass in the substantial absence of a melted matrix.
A method of forming a carrier-free pulverulent lubricant composition comprised of at least two particulate lubricant components, and at least one of which is graphite, comprising the steps of:
A carrier-free pulverulent lubricant composition comprising at least two particulate lubricant components, and at least one of said components being a metal soap, the particles of said composition consisting essentially of particulate lubricant components which have become fused together in a heterogeneous mass in the substantial absence of a melted matrix.
