This is an auto calytic deposition process. Here the PTFE particles are co-deposited along with Nickel - Phosphorous alloy deposit. The hardness of the nickel structure is 550 HV which can be raised to 750 HV by heat treatment.
 
Advantages of Nickel-PTFE Coating : 
 
• Low Friction Coefficient 
• Self Lubricating Surface 
• No stick / Slip Problems
• Uniform Coating Thickness 
• Good Corrosion Resistance
