Dry lubricants or solid lubricants are materials that, despite being in the solid phase, are able to reduce friction between two surfaces sliding against each other without the need for a liquid oil medium. [1] The two main dry lubricants are graphite and molybdenum disulfide. They offer lubrication at temperatures higher than liquid and oil ...
The appropriate lubricant for an automatic lubrication system can be determined using a Lincoln ventmeter. Factors such as the lubricant consistency, the diameter and length of the feed line and the operating temperature are taken into account. [7] The lubricant, be it oil or grease, is dispensed from a reservoir.
The Noack volatility test, named after Kurt Noack, [1] determines the evaporation loss of lubricants in high-temperature service. This test is standardized as ASTM D5800. [2] In this test, a sample is heated at 250 °C for 60 minutes with a constant flow of air over it. The weight fraction lost is the result for the Noack volatility test.
Fiber metal laminate (FML) is one of a class of metallic materials consisting of a laminate of several thin metal layers bonded with layers of composite material.This allows the material to behave much as a simple metal structure, but with considerable specific advantages regarding properties such as metal fatigue, impact, corrosion resistance, fire resistance, weight savings, and specialized ...
In used fluids, the oxidation products can be toxic as well. Lubricant persistence in the environment largely depends upon the base fluid, however if very toxic additives are used they may negatively affect the persistence. Lanolin lubricants are non-toxic making them the environmental alternative which is safe for both users and the environment.
The NLGI consistency number is also a component of the code specified in standard ISO 6743-9 “lubricants, industrial oils and related products (class L) — classification — part 9: family X (greases)”. [1] The NLGI consistency number alone is not sufficient for specifying the grease required by a particular application.
Solid film lubricants are paint-like coatings of very fine particles of lubricating pigment blended with a binder and other additives. The lubricant is applied to a substrate by spray, dip or brush methods and, once cured, creates a solid film which repels water, reduces friction and increases the wear life of the substrate to which it has been applied.

The company was founded in 1986 by John Williams, a synthetic oil developer and later consultant. Due to a customer who said he had never seen purple oil, Williams named the product Royal Purple. [6] Producing synthetic oil using its own additives, [7] the company grew and in 2004 completed a 125,000 square foot production facility in Porter ...
