The presented paper describes the topical problem in metal forging production. It deals with the choice of an optimal lubricant for forging of Al‐based alloys. Within the scope of the paper, the properties of several oil‐based colloidal‐graphite lubricants were investigated. The physicochemical and technological properties of these lubricants are presented. It was found that physicochemical properties of lubricant compositions have an influence on friction coefficient value and quality of forgings.
The ring compression method was used to estimate the friction coefficient value. Hydraulic press was used for the test. The comparative analysis of the investigated lubricants was carried out. The forging quality was estimated on the basis of production test. The practical recommendations were given to choose an optimal oil‐based colloidal‐graphite lubricant for isothermal forging of Al‐based alloy.
