Title:
METHOD FOR EVALUATING PERFORMANCE OF LUBRICATING LAYER
Document Type and Number:
WIPO Patent Application WO/2022/080402
Kind Code:
A1
Abstract:
A method for evaluating the performance of a lubricating layer according to the present invention comprises: a step for preparing a lubricant molecule model and a protective layer model by using a quantum chemical calculation; a step for performing a molecular dynamics calculation of an initial lubricating layer model constructed from the lubricant molecule model and the protective layer model; and a step for calculating an index of the adsorption degree of a lubricant molecule to a protective layer, from the results of the molecular dynamics calculation.
