10 Methods for Removal Chrome Plating
You must know the chrome plating. It is almost impossible to not know if you have worked on making glossy and shiny any material. But it is important to know about the basic information of coating anything on any material. And sometimes it is about removing the coat from the material which is harder than coating any material. Therefore, this article will present basic facts and information about removal chrome plating from different materials. This will start by discovering different removal processes then lead to different materials and pros and cons of chrome plating and finish removal.
How to Remove Chrome Plating: 10 Methods
Chrome plating is carried out electroplating which is adding a layer over metal of different material by surface treatment. This provides corrosion resistant to metal and improves its service life and adds beautification in product. However, there are many reasons that sometimes this coating is not so productive, and advantages and one must remove this. This is because it may be damaging the material instead of protecting it or must be torn so that it does not look so attractive. Therefore, one must know about the removal processes of chrome coating or finish removal from material which is discussed below:
Remove Chrome Plating Applications
Muriatic acid is also known as hydrochloric acid. It is a corrosive solution that is used for various reasons. It is also used in removal processes after surface treatments or for finish removal. It is a common solution for chrome removal from metal. This solution is taken in 30-40% concentration and added in water. The part is dipped in this solution until the plating is removed fully.
Mechanical Polishing
Special machines are used for removal processes of surface treatments. These machines are useful in metal and plastic finish removal. Abrasive blasting or sand blasting is the technique that is used in this removal processes. This involves abrasion of chrome plating by spraying of tine and fine particles. The tool used is called abrasive blaster. These are staples in auto shops. Because they can completely remove the plating from any material in automobiles.
Electrochemical Dissolution
Chemical solutions are used in electrochemical dissolution. Chromic and sulfuric acid are added to water and this solution is heated to a predetermined temperature for electroplating. It is connected to DC power source and a negative charge is passed through it. The material is connected to positive cathode. And then immersed in the solution. The removal process is carried out until the chrome plating is removed.
Thermal Decomposition
This removal process is consisted of heating material to the temperature 400-450℃. At this temperature range the applied chrome plating starts melting off. This can be removed safely from the material surface as the material cannot be damaged in this process.
Wet Etching
Hydrochloric acid is used as an etchant in wet etching removal process. The surface treatment can be removed easily by dipping the material in the diluted solution of water and hydrochloric acid b of 60/40 ratio. The material is dipped until the finish removal is done completely.
Dry Ice Blasting
Dry ice blasting is a common method for removing plating and coating. It can be used on metal, plastic, and rubber. Removal processes for surface treatment is not an easy process without damaging the material with cold jet system. But it is the best option for sensitive parts and hard chrome processes. The pellets are blasted at metals with high pressure by cold jet systems. It utilizes pellets that used 100cfm at 80psi. and micro pellets use 30cfm at 80psi. Low flow nozzles for micro pellets used 12cfm at 80psi.
Ultrasonic Cleaning
Ultrasonic cleaners use special cleaners for finish removal of surface treatment. It is normally used for sensitive and delicates parts. A high frequency sound wave is used to remove coating that is coating on surface. This causes a vibration in chrome particles at a higher frequency. This breaks the bond between plating and surface and resulted in flaking off the coating. However, this is an expensive process and not suitable for single parts or smaller objects.
Vapor degreasing
Vapor degassing can be used for stripping plating of chrome from metal and other materials. It involves condensing solvent vapor on the material and does not require any scrubbing or water. Instead use vapor for stripping plating or finish removal of surface treatments. Highly toxic chemicals like propyl bromide, perchloroethylene and trichlorethylene are used in degassers. The temperature range is kept between 40-65℃ with pressure of 25amps or less.
Lasers for removal
Laser removal is the safest removal process for stripping plating of surface treatment. As it does not damage the material and does not require any further treatment or cleanup. It can be used for smaller parts or delicate parts. Precision stripping plating is done on whether the area is a few feet or a few inches. Unique geometries can easily be cleaned without being damaged or impacted by laser ablation process.
Electrochemical Corrosion Control (ECC)
The ECC method involves attaching reactive metal to the material with a conducting wire for finish removal. It is carried out in water heaters and the weak metal is called anode. It is a safe method which can also remove rust and corrosion. In this process a thin coating layer of different material is coated on the other metal for various purposes or vice versa.
Remove Chrome Plating Applications
Chrome plating has many applications but sometimes it is damaging the material instead of protecting it when it is torn apart. Therefore, it is necessary to remove it.
