Abstract
There are provided a surface coating material for a molten zinc bath member with improved zinc corrosion resistance, a production method thereof, and a molten zinc bath member. The surface coating material comprises WC powder particles and a binder metal. The binder metal comprises Co and a metal element electrochemically nobler than Co and constitutes an alloy structure having a single phase.
Claims17
A surface coating material for forming a coated layer on a surface of a molten zinc bath member, wherein
- the surface coating material comprises WC powder particles and a binder metal, and wherein
- the binder metal comprises Co and a metal element electrochemically nobler than Co and constitutes an alloy structure having a single phase.
A method for producing a surface coating material for forming a coated layer on a surface of a molten zinc bath member comprising the steps of:
- producing an alloy powder comprising one or more of Ni, Mo, Si, Nb, Al, Cr, W, and Ta in addition to Co, by an atomization method or by a method of pulverizing a quenched thin strip or an alloy in a thin-strip or mass form obtained by casting;
- mixing the alloy powder with a WC powder to form a mixed powder;
- and
- granulating the mixed powder to obtain the surface coating material.
