When thinking of lubricants, most people think of oil or grease, the type that is used to reduce friction and enhance motion. These coatings address sliding and rotating issues and are designed to operate at temperatures well beyond where liquid lubricants, such as oils and greases fail or cannot be used at all. They fall into a number of classes including Extreme Thin Film, Conformal, Build-up, and Release/Non-stick. The Coatings can include more than one benefit. As an example; a coating to build up the dimensions of a component can also have excellent chemical and corrosion resistance. Others can also aid in the heat management of components. The proper selection can lead to lower friction, increased part life, the ability to run tighter tolerances, the ability to have a coating conform to the needed dimension when running, and lower operating or part temperature.
Dry-Film lubricants are formulated with solid lubricants, such as molybdenum Disulfide (MoS2), PTFE and graphite, and binders. Applied like a coating, they form a lubricating film at room temperature or after being dried by heating. Applicable to diverse parts, such as metals, plastics, and rubbers. These are ideal for applications aimed at improving initial running-in, wear resistance, adherence prevention and low friction performance, those involving locations where oil and other normal lubricants cannot be used, and those based on a desire to achieve a synergy effect with such lubricants.
Solid lubricant coatings possess inherent lubricating properties and hence are very attractive for use under severe application conditions (such as high vacuum, aerospace, high speeds, high loads, and very low or high temperatures), where conventional materials and lubricants cannot provide the desired levels of performance or durability.
IT-2550 is a moly based, one component aqueous lubricating coating designed for cold forming of iron and steel. It is a concentrate and is diluted with water before use. Cleaning of billet surfaces by shot-blasting helps the film form a uniform and adherent coating which provides adequate lubrication during cold forming operations.
For heavy forging processes a phosphating can be beneficial.
IT-2550 provides the following features:
• High forging degrees possible.
• No flying dust & hence less pollution.
• Parts with near net-shape; best surface quality.
• No contamination of the dies.
• Improved life of the tooling.
• Shortened processing time.
