Title:
ガルバニール平鋼製品の摩耗特性を測定する方法および装置
Document Type and Number:
Japanese Patent JP6470293
Kind Code:
B2
Abstract:
The invention relates to a method for determining the abrasive-wear properties of galvannealed flat steel products (2). In order to be able to characterize the abrasive-wear properties of a coated flat product objectively, meaningfully, and reproducibly, a method of the stated type is proposed, wherein an adhesive strip (7) is adhesively bonded to each flat steel product (2), the flat steel products (2) are bent in the area provided with the adhesive strip (7) or to be provided with the adhesive strip (7) in order to produce abrasive wear of the zinc coating, the adhesive strips (7) are removed together with abrasive wear of the zinc coating adhering to the adhesive strips (7) after the bending of the flat steel products (2), a physical dimension and/or a representative gray value of the abrasive wear adhering to the adhesive strips (7) is determined, the iron concentrations of the zinc coatings of the respective flat steel products are at least partially determined, and the dependence on the physical dimensions and/or the representative gray values of the abrasive wear adhering to the adhesive strips (7) on the iron concentration of the zinc coating is determined.
