VV BN 7 O 0a + ?Z 1 A BNb Abstract : It is a general trend to replace Chrome by Tri-chrome for passivation of Zinc and Zinc alloy plating due to environment protection issue.
2、Tri-chrome technology is mature and available nowadays. Its performance has not only reached or exceeds the level of Chrome in corrosion resistance, but also is obviously better than chrome in temperature resistance, Zinc alloy passivation, and satisfying some special mechanical demand. 1oM N Key Wo
