Metal Finishes Flashcards
- mechanical means
- applied on a metallic substance
- includes cleaning and chemical pre-treatment; 1 or 2-side, single or multiple application of liquid or powder coating materials
Coating (organic)
- non-metallic coating
- coating with a non-transparent formulation containing pigments
Painting/ Enameling
- non-metallic coating
- coating with a formulation based on a dissolved material which forms a transparent layer after drying; increases corrosion resistance
Lacquering
- non-metallic coating
- dip coating; steels are dipped in this; looks like latex paint
Plastic and Nylon Coating
- mechanical means
- continuous coating of a material strip; applied in steel and aluminum
Coil Coating
- mechanical means
- single coating of any type with no particular requirements for appearance
- usually reverse side of the coated product
Backing Coat
- mechanical means
- treatment of metal with chemical solutions by dipping or spraying to build up an oxide film
Chemical Conversion Coating
- mechanical means
- application of a priming paint
Priming
- mechanical means
- application of a solution (resin, chromate, and acid)
Pretreatment Priming
- mechanical means
- single coating; like primer with special properties regarding adhesion and corrosion protection
Single Coat System
- mechanical means
- system comprising with a primer or a base coat, intermediate coat(s), and a top coat
Multiple Coat System
- mechanical means
- dry paint film of the coated product
Organic Coating
- mechanical means
- organic film applied to a substrate
Film Coating
- mechanical means
- process of applying a thin coating of an expensive anti-corrosive metal
- chrome plate, nickel plate, bronze plate, silver plate, zinc plate
Metallic Coating
- chemical means
- chemical treatment to improve the optical reflectivity of a surface
Chemical Brightening
- chemical means
- polishing of metal surface by immersion in a solution of chemical reagents
Chemical Polishing
- chemical means
- removal of oil or grease by a suitable organic solvent
Degreasing
- chemical means
- roughening of the surface of a metal by overall or selective dissolution in acid
Etching
- chemical means
- removal of a thin surface layer of a metal by chemical action
Pickling
- chemical change accompanying the passage of an electric current
- removes metal in a selective manner
Electrochemical means
- electrochemical means
- treatment to improve the optical reflectivity of a surface
Electrochemical Brightening
- electrochemical means
- polishing of a metal surface by making it anodic in an appropriate electrolyte
Electropolishing
- electrochemical means
- produced by an electrolytic oxidation process in which the metal is converted to a mainly oxide coating having protective, decorative or functional properties
Anodized Metal
- electrochemical means
- metal with a colorless, translucent anodic oxidation coating
Clear Anodized Metal
- electrochemical means
- anodized metal colored either during anodizing or by sub sequent coloring processes
Color Anodized Metal
- electrochemical means
- metal that has been anodized using an appropriate electrolyte; produces a colored coating
Integral Color Anodized Metal
- electrochemical means
- colored by electrolytic deposition of a metal or metal oxide
Electrolytically Colored Anodized Metal
- electrochemical means
- colored by absorption of dye-stuff or pigments
Dyed Anodized Metal
- electrochemical means
- colored by electrolytic coloring or produced by integral color anodizing followed by absorption dyeing
Combination Color Anodized Metal
- electrochemical means
- colored by means of optical interference effects
Interference Color Anodized Metal
- electrochemical means
- anodized metal with a high specular reflectance
Bright Anodized Metal
- electrochemical means
- anodizing wherein the primary characteristic is protection against corrosion or wear
Protective Anodizing
- electrochemical means
- anodizing wherein a decorative finish has a uniform and esthetically pleasing appearance
Decorative Anodizing
- electrochemical means
- anodizing to produce a finish to be used in permanent, exterior, and static situations
- importance of appearance and long life
Architectural Anodizing
- electrochemical means
- anodized metal with a wear and/or abrasion resistant anodic oxidation coating
Hard Anodized Metal
- electrochemical means
- treatment of anodic oxidation coatings on metal to reduce porosity and absorption capacity of the coating by hydrothermal processes
Sealing
- electrochemical means
- treatment of anodic oxidation coatings on metal to plug pores and reduce absorption capacity of the coating by chemical processes carried out at low temperatures after anodizing
Cold Impregnation
- electrochemical means
- use of a colored powder (with a positive electric charge) that is sprayed onto a metal (with a negative electric charge) and baked in kiln to fuse powder to metal surface
- ideal for exterior applications
Powder-coating
