electroless nickel a-carbon treatment                                     

 
 

If in the coating companies diverse basic materials are coated the result is that at working temperatures of 80 to 92 °C constant interactions with the surfaces of the raw parts in such way take place that corresponding pouring-, dragging- and other auxiliary means of the surface-near layers of the raw parts are set free and get to the electroless nickel bath.  

Consequence: Due to the increase of these “auxiliary means”, paired with an increasing shelf life the deposited layers will be matt or blockages/faulty coatings or other quality problems occur.

In many cases the electroless nickel supplier is doubted. This is a big error !

Remedy: With an a-carbon treatment these “auxiliary means” will be deprived from the electroless nickel bath. Then the deposited layers are flawless again !

Diverse approaches from working under practical conditions are known.

New active carbon filter cartridge. Active carbon filter cartridge after 3 weeks contact with HCl-pickle.

Unmistakably, pouring-, dragging- and other auxiliary means from the base material. The HCl-pickle is now clear. The bottom of the tank is clearly visible. A preventive anti-contamination measure within the electroless nickel electrolyte !
