Next, I will share with you the knowledge of rust prevention for mechanical castings.

The corrosion or discoloration of metals or alloys in the atmosphere caused by oxygen, moisture, acid, salt, and humid air is called rust or corrosion, which can turn a very metallic surface into a low strength compound. For this reason, investment castings often require mid-term rust prevention treatment. The method of rust prevention usually involves using water or oil to prevent rust. Regardless of which method is chosen for rust prevention, castings must be washed in advance to remove surface contaminants and generate a passive film. The composition, temperature, and purpose of the washing solution. After washing the castings, they should be dried with hot and dry compressed air and then subjected to rust prevention treatment.
