Title:
FRICTIONAL COEFFICIENT PREDICTION METHOD, ALUMINUM METAL PLATE PRODUCTION METHOD, MOLDED ALUMINUM BODY PRODUCTION METHOD AND ALUMINUM METAL PLATE
Document Type and Number:
WIPO Patent Application WO/2020/049905
Kind Code:
A1
Abstract:
According to one aspect of the present invention, the frictional coefficient prediction method for an aluminum metal plate surface uses the skewness Rsk and the arithmetic mean roughness Ra of the surface to predict the frictional coefficient μ via formula (1).
(1) μ = a + b × Ra + c × Rsk ···
In the formula, a, b and c represent constants
