AMORPHOUS IRON ALLOY CONTAINING CARBON WITH HIGH CORROSION RESISTANCE

Title:

AMORPHOUS IRON ALLOY CONTAINING CARBON WITH HIGH CORROSION RESISTANCE

Document Type and Number:

Japanese Patent JPS58126960

Kind Code:

A

Abstract:

PURPOSE: To obtain an amorphous Fe alloy contg. C with high corrosion resistance by restricting the composition of an alloy consisting of Fe, Cr, Mo and/or W, and C and by rapidly cooling the alloy from a liq. state.

CONSTITUTION: This alloy has a composition represented by the formula (where M is Mo or W, Q is C, a is 28W82 atomic%, b is 0W20 atomic%, c is 4W26 atomic% and d is 12W26 atomic%). The alloy is melted, sprayed on an opposite copper plate for cooling by means of highly pressurized N2, Ar or other gas, and solidified by rapid cooling in the form fine powder to manufacture amorphous alloy powder. This alloy has superior corrosion resistance 105W108 times the corrosion resistance of commercially available high grade stainless steel.
