Shenzhen Nearjin Surface Technology Co., Ltd

Green healthy woks with' high security, no coating, antiseptic treatment, wear resistance' is one of successful technology application example

In mechanical working, this technology has a obvious advantage of anti-dilute acid, is far better than other technologys, such as QPQ Salt bath, Nitri

Unlike traditional surface hardening technology is difficult to adapt to the porous nature of powder metallurgy and thermal deformation, it improved t
