摘要：

The main purpose of this work is to evaluate the tribological behaviour of austenic stainless steels AISI 304 with bright annealed surface finishing (BA) (ASTM a 240); AISI 304 DDQ and AISI 316 with bright Surface finishing (B). The assays have been carried out in flat faced dies system with mineral oil of 200 cts viscosity, S(2)Mo grease and in dry conditions.. The relationship between friction coefficient and pressure and velocity has been established for the mineral oil as lubricant. In these conditions, a strong adhesive tendency has been found in boundary lubrication regime. The results obtained here, show us that S2Mo grease leads to lowest values for the friction coefficient. A minor adhesive behaviour tendency for AISI 316 steel, harder than 304 grades, has been found. A relevant plowing phenomena has been observed for the more critical friction conditions tried out. A surface hardener is produced as 2 consequence of that.
