Welcome to our comprehensive suite of finishing services, where precision and quality are at the forefront of our operations. At Davro, Inc., we specialize in enhancing the performance, durability, and aesthetics of various metals through advanced processing techniques. Our services include:
Passivation
Passivation is a finishing process that enhances the corrosion resistance of stainless-steel. This process is typically done in a Nitric or Citric Acid solution. By removing free iron from the surface, this process results in an inert oxide layer that improves corrosion resistant properties.
Titanium Alpha Case Removal
Titanium Alpha Cases are the hard brittle surfaces of titanium forgings exposed to heat or oxygen. These alpha cases can develop micro-fractures that will reduce the metals performance and longevity. Acid Pickling is used to remove this layer and improve the performance of the material.
Electropolish
Electropolishing is an electrochemical process that removes material from the surface, reducing surface roughness by flattening out micro-peaks & valleys in the surface of the metal. This results in a superb visual appearance, and enhanced corrosion resistance. This is often followed up with a passivation process to further increase the corrosion resistance.
Pre-Penetrant Etch
Pre-Penetrant etching is the process of of removing foreign material or blemishes from the surface of a material to prepare it for Fluorescent Penetrant Inspection. This is achieved by Acid Pickling of the material.
Chemical Cleaning of Aluminum
Chemical Cleaning of Aluminum alloys removes foreign contaminants and surface defects to provide a uniform surface.
Pickling
Pickling removes free iron from the surface of stainless steel. This is performed prior to the passivation process to remove oxide scale or heat treat tint.
DAVRO INC. Warranty Policy
“Due to the nature of our processes, Davro Inc. does not offer a traditional warranty. However, we guarantee that all services are performed in strict accordance with customer specifications, industry standards, and validated procedures. The quality of our service is verified through rigorous final inspection processes. Any issues identified before shipment will be addressed and corrected at no additional cost to the customer. The long-term effectiveness of the chemical processing treatment is contingent upon the customer’s proper handling, storage, and usage of the treated parts.“
