Title:
摩擦係数予測方法、アルミニウム金属板の製造方法及びアルミニウム成形体の製造方法
Document Type and Number:
Japanese Patent JP7017487
Kind Code:
B2
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
