Customized Nanocoating on Titanium Substrate

Titanium and titanium alloys have outstanding properties of low density, low modulus of elasticity, high specific strength, high corrosion resistance and good biocompatibility. Alfa Chemistry offers unique functionalized coatings for titanium substrates, which alloys with functional surfaces offer various performance advantages in a wide range of applications. You may improve the performance of practically any titanium-based product with our broad and simple-to-apply specialty coating treatment methods. Please collaborate with us to make your titanium and titanium alloy surfaces functional!

Extensive Surface Modification Technology Options

Alfa Chemistry offers a number of coating processes that can be used to functionalize titanium surfaces and provide a number of performance advantages. Our titanium steel substrate surface modification technology options include but are not limited to the following.

• Surface Waterproofing Coating Technology - We can functionalize titanium substrate surfaces to be highly water and oil repellent, as well as highly repellent to practically all liquids, using surface waterproofing coating technology.
• Hydrophilic Coating Technology - The surface of titanium substrates can be functionalized to make them very hydrophilic.
• Adhesion Promotion Coating Technology - We can functionalize the surface of titanium substrates to improve the adhesive capabilities of the surface using adhesion promotion coating technology.
• Particle Modification Coating Technology - Alfa Chemistry's particle modification coating technology can improve particle behavior, minimize aggregation, and optimize cross-linking by functionalizing titanium powder and particle surfaces.
• Lubricant Coating Technology - We can functionalize the surface of titanium substrates to reduce surface friction.

These nanocoatings are optically transparent and highly durable.

Alfa Chemistry Coating Solution Cases

Case 1: Multicomponent GtO/HA/Sodium Alginate Coating

A multicomponent sodium alginate-based coating enhanced with hydroxyapatite (HA) nanoparticles and graphite oxide (GtO) nanoflakes consisting of graphene oxide (GO) encapsulation was electrophoretically deposited on a titanium-zinc alloy.  The sodium alginate generated a continuous coating matrix with a rather uniform distribution of HA nanocrystal clusters and GtO flakes. The titanium alloy's corrosion resistance was increased by the coating, which had outstanding hydrophilic characteristics and a high surface free energy.

Case 2: The nano-Cu-MOF polydopamine coating

Nitric oxide (NO) improves anticoagulant and antiproliferative ability. Copper-based metal-organic backbone materials have been demonstrated to have significant potential as NO catalysts, and copper ions (Cu) have been shown to enhance endothelial cell development (EC).

Alfa Chemistry used polydopamine as a linker and coating substrate to immobilize nanoscale copper-based metal-organic backbones (nano-Cu-MOFs) on a titanium surface, catalyzing the formation of nitric oxide (NO) and Cu delivery at the same time. This coating reduces thrombus formation by inhibiting platelet aggregation and activation via the NO-cGMP signaling pathway.
