A hot dip galvanizing roll used to change the steel sheet passing direction from downward to upward while holding the steel plate in the hot dip galvanizing bath in equipment for dipping zinc in the hot dip galvanizing bath. In order to prevent the wear of the steel sheet, a stainless steel type material is usually used. However, in this case, the roll is soaked in molten zinc, and since the bath composition and the metal layer are formed, unevenness is generated on the roll surface, causing a flaw in the plated product,
In addition to the conventional roll materials, thermal spraying cermet and ceramic coatings have been proposed.

題がある。However, in the case of the self-fluxing alloy as disclosed in Japanese Patent Laid-Open No. 59-153875, which is the above-mentioned prior art, after forming a film by thermal spraying, a remelting process usually called refusing is performed. Although the porosity is eliminated by doing, the metal-based coating such as self-fluxing alloy reacts with zinc, and the life of the coating is short when used in a zinc bath, and when the pores are not completely eliminated, Zinc penetrates from that portion and attacks the roll base material. Further, in the vicinity of the interface of a roll having a high Co or Ni concentration forming a high-viscosity compound containing Co and Ni, which is added as a bonding material for a cermet material as in Japanese Patent Laid-Open No. 1-225761, a gel is formed. However, there is a problem that a flaw is imparted to the steel sheet by the roll after the compound is attached to the steel sheet or the zinc is solidified by plating the compound.

めである。In this way, the cermet film on the roll surface, the cermet film and the oxide ceramic film
A cermet film is formed on a layer film and an alloy film containing Co or Ni, and a three-layer film of an oxide-based ceramics film is formed on the uppermost layer. These films remain because they are sprayed under vacuum or reduced pressure. There is no or very little air in the pores, or in the atmosphere, it is sprayed with a high-velocity flame to bring the porosity to an extremely small value. In this way, after the coating is formed on the surface of the roll by thermal spraying, the treatment is carried out in a high temperature, high pressure nitrogen or argon atmosphere furnace.
That is, the nitrogen or argon atmosphere temperature is 700 to 13
Set to 00 ° C. This is because the mutual diffusion rate is extremely slow when the temperature is lower than 700 ° C. The upper limit temperature is set to 1300 ° C because the roll base material is deformed when the temperature exceeds 1300 ° C.

After coating with the cermet material, ZrO 2 partially stabilized with CaO is sprayed on the upper layer, and the roll is HIPed.
Treatment (hot isostatic pressing method) After charging into a container and replacing with nitrogen, temperature 1200 ° C, nitrogen pressure 2000 kg /
It was held at cm 2 for 8 hours. The porosity of the film of the sample piece attached to the roll portion after retention was 99.5% as measured. The porosity was measured by enlarging the cross section of the film up to 1000 times and taking a photograph, and then measuring the area ratio of the pores with an image sensor, and taking the value as the porosity. As a result of the interface analysis after the HIP treatment, the roll base material and the cermet and the bonding interface between the cermet and the oxide-based ceramic film were sufficiently interdiffused, and the mutual adhesion was extremely good. As a result of continuously using the roll in a zinc bath,
Although the conventional roll has a life of 60 days, the roll of the present invention can extend the life to 150 days, that is, 2.5 times longer, and can reduce the roll replacement and maintenance cost. It was
