Shot peening is a cold working process used to enhance the mechanical properties of metal parts. By bombarding the surface with small spherical media, known as shots, we create compressive residual stress layers that improve the part’s fatigue strength and resistance to stress corrosion cracking.

Aluminum chromate, or chromate conversion coating, is a chemical process applied to aluminum surfaces to enhance their corrosion resistance and adhesion properties. This treatment forms a protective layer on the metal, preventing oxidation and degradation in harsh environments. The process involves immersing aluminum parts in a chromate solution, which reacts with the metal to form a thin, durable coating.

Spray coating is a process where a coating material is applied to a surface using a spray gun. This method allows even coating distribution, ensuring a smooth and consistent finish. The technique can be used to apply paints, varnishes, powders, and other coating materials to enhance the products’ appearance, durability, and performance.

The main difference between sandblasting and bead blasting is the material used and the result. Sandblasting uses rough sand particles, which can be aggressive. This makes it great for heavy-duty cleaning. Bead blasting, however, uses smooth, spherical beads. It creates a gentler finish, better for delicate surfaces or when you need more precision.

Pad printing is a printing method used to apply 2D images onto 3D objects. It works through an indirect process. A soft silicone pad picks up ink from an engraved plate and presses it onto the surface of a product. The plate, also known as a cliché, holds the image. The pad transfers the image by wrapping around the shape of the object.

Anodizing creates a protective oxide layer on the metal surface, offering exceptional durability and corrosion resistance. It’s ideal for aluminum parts, enhancing both aesthetics and functionality. Powder coating provides a thicker finish with various colors and textures, suitable for metals like steel and aluminum. Each method has strengths and depends on your specific requirements.

Sandblasting aluminum oxide means using high-pressure air to shoot sharp aluminum oxide grains at a surface. These grains hit the surface and strip away rust, paint, or dirt. They also create a rough texture that helps paint or coatings stick better.

Painting over anodized aluminum requires careful preparation to ensure the paint adheres and lasts. First, clean the surface thoroughly to remove any contaminants. Then, use a primer designed for metal, especially one suitable for anodized surfaces. This helps the paint stick better and extends the life of your paint job.

Clean the anodized surface with a soft, soapy cloth and water. Rinse and then dry the surface. Apply a small quantity of high-quality metal polish to a microfiber towel and rub gently in circular motions. Remove any excess polish using a clean, dry cloth. Finish with a silicone spray and buff lightly to increase the shine.

Titanium anodizing is an electrochemical process. It changes the oxide layer on the surface of titanium. This layer controls how light reflects off the metal, creating different colors. The thicker the coating, the more the color shifts.

Alodine coating, also known as chem film or chromate conversion coating, is a chemical treatment applied to aluminum. It creates a protective shield on aluminum parts. The primary purpose is to prevent corrosion, which can weaken metal parts over time. Additionally, it prepares the surface for painting or other finishes by improving adhesion.

Phosphating is a chemical process in which a phosphate coating is applied to a metal surface. This coating is a difficult-to-dissolve transformation layer composed of metal phosphates. It acts as a protective layer, shielding the metal from corrosion, wear, and other environmental damage.

Phosphating works through chemical reactions between the metal surface and a phosphate solution. When the metal is immersed in the solution, the phosphoric acid reacts with the metal ions to form a layer of insoluble phosphate crystals.

E-Coating, or Electrophoretic Deposition, refers to a specific type of paint applied to metal parts. It involves immersing the parts in a bath of paint particles suspended in water. When we apply an electric charge, the paint particles stick to the metal surface.

Getting good results when grinding stainless steel starts with choosing the right tools and methods. Use aluminum oxide or ceramic abrasives made explicitly for stainless steel. Keep the metal cool during grinding to avoid heat discoloration. Work with light to medium pressure and move constantly to prevent overheating one area.

Metal burrs can be small and sharp protrusions on metal edges after machining operations such as drilling or milling. These are bits of metal that have not been removed cleanly from a part. They can leave a jagged or rough edge.

Nickel plating is a process that applies a thin layer of nickel to a metal surface using an electrochemical method. The nickel layer adds extra protection and improves the metal’s appearance.

Nickel plating creates a protective barrier that prevents oxidation and surface damage. It extends the lifespan of stainless steel components and enhances their performance in harsh environments. Industries use it for both functional and decorative purposes.
