Customized Nanocoating on Chromium Substrate

INQUIRY

Chrome is a silver-gray metal that is hard, brittle, and valuable. To withstand rust and corrosion, it is thoroughly polished. Polished chromium metal reflects approximately 70% visible light and nearly 90% infrared light. The strong corrosion resistance and hardness of chromium metal make it valuable. The key additive to stainless steel is chromium, which gives it corrosion resistance.

Alfa Chemistry offers unique functionalized coatings for chromium substrates, and chromium metal with a functional surface offers significant performance advantages in a number of applications. You may increase the performance of practically any chrome-based product with our broad and simple-to-apply specialty coating treatment solutions. Collaborate with us to make the surface of your chrome substrates useful!

Extensive Surface Modification Technology Options

Alfa Chemistry has a variety of surface modification technologies that can functionalize the surface of chrome as well as its alloys to provide numerous performance benefits. Our surface modification technology options for chrome and gold include, but are not limited to:

  • Surface Waterproofing Coating Technology - We can functionalize the surface of chrome substrates to be highly water and oil repellent, making them highly repellent to almost any liquid.
  • Hydrophilic Coating Technology - We are able to functionalize chrome substrate surfaces to be highly hydrophilic.
  • Adhesion Promotion Coating Technology - We can functionalize chrome substrate surfaces to enhance the adhesion properties of the surface.
  • Particle Modification Coating Technology - Alfa Chemistry can functionalize chrome powders and particles to improve particle behavior, eliminate aggregation, and optimize cross-linking.
  • Lubricant Coating Technology - We can functionalize chrome substrates to reduce surface friction.

The coatings we can build are nanoscale, optically transparent and highly durable.

Alfa Chemistry Coating Solution Cases

Case 1: Protein biocoating

As bone growth stimulators, bone morphogenetic proteins (BMPs) have been the focus of substantial research and clinical studies. Ionic groups or hydrophobic residues can be attached to the metal surface to create protein-binding surfaces. Alfa Chemistry prepares rhBMP-2 and ubiquitin on cobalt-chromium-molybdenum alloys for recombinant human BMP-2 (rhBMP-2) and ubiquitin adsorption. rhBMP-2 and ubiquitin bind very securely to surfaces with a particular surface concentration of propyl or hexyl groups and release slowly over at least 24~100 days, allowing such surfaces to be employed as long-term drug delivery systems for increased bone formation or implant integration.

Case 2: Biodegradable polymer-based cobalt-chromium scaffolds

Restenosis rates after coronary angioplasty can be reduced by drug-eluting coronary stents. porous carbon-carbon nanoparticle have showed promise as drug adsorption and delivery carriers. These materials are biologically inert, have good elastomechanical properties, and allow drug release kinetics to be tweaked by changing the pore size.

On drug-eluting cobalt-chromium scaffolds, we can create porous carbon-carbon nanoparticle coatings. This preclinical study shows that innovative cobalt-chromium scaffolds with carbon-carbon coatings and low and medium paclitaxel dosages are safe and effective.
