Abstract
A method for determining the abrasion resistance of at least one wear layer arranged on a carrier plate, including: capturing at least one NIR spectrum of the wear layer arranged on the at least one carrier plate using at least one NIR detector and determining the abrasion resistance of the at least one wear layer by comparing the NIR spectrum for the abrasion resistance that is to be determined with at least one NIR spectrum ascertained for at least one reference sample by multivariant data analysis (MDA).
Claims20
A method for determining the abrasion resistance of at least one wear layer arranged on at least one core board comprising the following steps:
- recording at least one NIR spectrum of the at least one wear layer arranged on the at least one core board
- a) before hardening of the at least one wear layer,
- b) after hardening of the at least one wear layer, or
- c) before and after hardening of the at least one wear layer with the at least one core board with use of at least one NIR detector in the wavelength range from 500 nm to 2500 nm;
- by means of multivariate data analysis (MDA), determining the abrasion resistance of the at least one wear layer by comparing the NIR spectrum recorded for determining the abrasion resistance of the at least one wear layer with at least one NIR spectrum recorded for at least one reference sample of the at least one wear layer with known abrasion resistance,
- where the at least one NIR spectrum recorded for the at least one reference sample with known abrasion resistance of the at least one wear layer has been determined in advance a) after hardening or b) before and after hardening with use of the same NIR detector in the wavelength range from 500 nm to 2500 nm.
