The Surface Coating of Car Bodies
Step 2 Phosphating The metal is treated with phosphoric acid, leading to the following two reactions occuring in the zinc-rich surface of the steel: 2H3PO4 + 3Zn → 3H2 + Zn3(PO4)2 2H3PO4 + Fe + 2Zn → 3H2 + FeZn2(PO4)2 This gives a mixture of zinc phosphates. The electrocoat paint binds better to these zinc phosphates than to the steel alone, and the zinc phosphates corrode much slower than the ...
متن کاملMicroneedle Coating Techniques for Transdermal Drug Delivery
Drug administration via the transdermal route is an evolving field that provides an alternative to oral and parenteral routes of therapy. Several microneedle (MN) based approaches have been developed. Among these, coated MNs (typically where drug is deposited on MN tips) are a minimally invasive method to deliver drugs and vaccines through the skin. In this review, we describe several processes...
متن کاملComparison of Lift and Drag Forces for Some Conical Bodies in Supersonic Flow Using Perturbation Techniques
Numerical methods are not always convergent especially in higher velocities when shock waves are involved. A comparison analysis is performed to study the supersonic flow over conical bodies of three different cross sections circular, elliptic and squircle (square with rounded corners) shaped using Perturbation techniques to find flow variables analytically. In order to find lift and drag forc...
متن کاملAlternative technique for calcium phosphate coating on titanium alloy implants
As an alternative technique for calcium phosphate coating on titanium alloys, we propose to functionalize the metal surface with anionic bath containing chlorides of palladium or silver as activators. This new deposition route has several advantages such as controlled conditions, applicability to complex shapes, no adverse effect of heating, and cost effectiveness. A mixture of hydroxyapatite a...
متن کاملAcid aluminum phosphate for the binding and coating of materials
This is a review of acid aluminum phosphate for the binding and coating of materials. The acid aluminum phosphate in the form of a solution obtained by dissolving aluminum hydroxide in phosphoric acid, with a P/Al molar ratio of 23, is effective for the binding of fibrous or particulate materials. Porous ceramic articles are made using this binder by wet forming, followed by heat treatment. The...
