X-ray spectral analysis of surface structures formed on copper alloys during film fasting

Abstract

The paper establishes the nature of the redistribution of chemical elements and their concentration in secondary surface structures for the material systems "steel 45XN2MFAgrease- BrOTsS4-4-2.5", "steel 45XN2MFA-grease-BrOTsS4-4-4", "steel 45XN2MFA-grease - L-63 ", tested under the conditions of simulating film starvation when lubricated with 15W40 Lukoil-Super SAE SG/CD engine oil. Since the formula obtained by us includes the Gibbs energy, the self-organization of the structure under consideration naturally also enters. General laws of self-organization are observed when a number of conditions are met: irreversibility, openness (nonequilibrium), nonlinearity, instability (coherence), dissipativity. All these elements were observed and described by us in this work. It is due to self-organization that the distribution of chemical elements carbon and oxygen occurred on the surfaces L63 and BrOF4- 4-4. To this effect must be added a decrease in the surface tension of the lubricant.
