Titanium substrate pretreatment:

Surface titanium oxide film is formed easily purified, its conductivity is poor, and titanium in the process easily contaminated with oil, will lead to the conductivity of Grade 9 Titanium components decreases, resistance increases, while the coating with the titanium can not plate surface closely. Therefore, in order to improve the conductivity of the electrode, the bonding coating and substrate more closely, and in order to remove stains produced during machining titanium, etc., to ensure that telephone and coating properties of the active electrode, titanium substrate make the necessary pre- deal with.
