Research shows that due to the potential difference between titanium and steel tools in alkaline solution, there is a galvanic cell effect. When titanium comes into contact with steel, a galvanic current is formed. The smaller the contact point, the greater the current. If the contact point is too large, The current density causes localized overheating, so that the titanium rod often begins to burn at the point of contact between the two metals.

In order to prevent and reduce the ignition of titanium rods during alkali cleaning, the following measures can be taken:
1. Select qualified alkali cleaning liquid ingredients;
2. Strictly control the temperature of the alkali solution;
3. Use high temperature resistant coating or high temperature resistant insulating gasket to insulate the alkali cleaning frame. If a stainless steel alkali cleaning frame is used, ceramic strips or sheets can be padded to separate the titanium material from the steel frame, which can also prevent fire.

During the alkali cleaning process of titanium rods, the alkali solution is constantly taken away or evaporated by the workpiece, so it is necessary to replenish the alkali solution and make timely adjustments to keep the alkali solution composition relatively stable. During alkali cleaning, insoluble oxide scale residue precipitates at the bottom of the tank, affecting the good thermal conductivity of the tank. Moreover, the gaps caused by the precipitation make the steel tank prone to electrochemical corrosion, greatly shortening its service life. Therefore, the sediment must be cleaned up in time. Using a movable tank bottom to collect slag is a common method. When sediment needs to be eliminated, just lift the bottom of the movable tank away.
