Title:
STAINLESS STEEL HAVING EXCELLENT SURFACE ELECTRIC CONDUCTIVITY, AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2010209405
Kind Code:
A
Abstract:
To provide stainless steel having high surface electric conductivity in a solid state, and mass-producible.
The stainless steel contains Mo in a coating film on a surface of base steel. In the Mo content in the coating film, the ratio of Mo occupied in Cr, Al, Si, Fe and Mo by the X-ray photoelectron spectroscopy analytical method (XPS) is ≥10 atom%, the Mo content is the index indicating the ratio of Mo and MoO2out of Mo component present in the coating film. The stainless steel has excellent surface electric conductivity in which the value A by the formula: =(hMo+hMoO2)/(hMo+hMoO2+hMoO3) is ≥0.3, where hMo, hMoO2and hMoO3denote the peak intensity attributable to the bond energy of Mo, MoO2and MoO3in the XPS spectrum of the coating film, respectively.
