Abstract

Phthalocyanine and salts of phthalocyanine are useful as solid lubricants. The application to and maintenance of phthalocyanine-type compounds on complex surfaces and surfaces which are subject to continuous wiping can present a problem. Application and maintenance are achieved by wiping the article with a flexible web containing the solid lubricant.

Solid Lubricant System

Phthalocyanine and salts of phthalocyanine are useful as solid lubricants. The application to and maintenance of phthalocyanine-type compounds on complex surfaces and surfaces which are subject to continuous wiping can present a problem. Application and maintenance are achieved by wiping the article with a flexible web containing the solid lubricant.

For example, in some recording systems magnetic recording heads of metal or ceramic composition are subjected to constant wiping with magnetic media. By incorporating phthalocyanine in or on a recording media, a stable solid lubricant coating is built up upon the head during running of the head and the media in normal wiping relationshipship. The lubricant is maintained on the head due to the constant resupply of material from the media.

While phthalocyanine-type compounds may be included in all media run in contact with the head, it may be possible to selectively, from time-to-time, introduce a lubricant-carrying media into use with the head. In other operations, it may be possible to utilize a lubricant containing carrier, other than a magnetic media, to lubricate the head.

Utilizing this technique, it is also possible to provide a coating of solid lubricant, such as phthalocyanine, on surfaces other than heads by continuous or intermittent wiping of the surfaces with a lubricant containing carrier.
