ALTERING AND ADDING METAL FINISHING PROCESSES
To change the surface of a part or product, metal
finishing processes are added to or altered. In
order to achieve desired features and attributes,
such as better durability, aesthetics,
solderability, and chemical resistance, a layer
of the desired material is added rather than
being removed or reshaped.

TYPES OF METAL FINISHES
A metal product or component's exterior can be
finished by forming a thin layer of enhancing
material or by removing material from the
component's surface.

• ELECTROLESS PLATING

Chemical plating, also known as electroless
plating or auto-catalytic plating, is a method of
metal processing that uses chemicals to coat
metal rather than electricity

2. PASSIVATION
The chemical process of passivation makes a
material passive, or less prone to corrosion.
Corrosive particles are eliminated by immersing
parts in a solution of nitric or citric acid.

3. ELECTROPLATING
Electroplating is also referred to as
electrodeposition onto the surface of a metal
part or component, known as a substrate, during
the metal finishing process of electroplating,
also known as electrodeposition. In the process
of electroplating, a substrate materialtypically
one that is lighter and less expensiveis
enclosed in a thin layer of metal parts cleaning
services Cincinnati, such as copper or nickel.

4. BUFF POLISHING
An alternative to electropolishing that doesn't
use the electrochemical process is buff
polishing. Like buffing a car, buff polishing
involves using a machine with a cloth wheel to
clean and buff the surface of your components.

5. HOT BLACKENING
Hot blackening is a metal finishing process that
coats the surface of a substrate with a thin
layer of black oxide. Hot blackening is commonly
used by manufacturers to increase the abrasion
resistance of metal finishing Cincinnati parts
and provide a black matte finish on automotive
parts, firearms, and military applications that
require a protective dark coating.

6. PHOSPHATE COATING
Phosphate coating, also known as phosphatization,
is a chemical treatment commonly used on steel
parts and other metals such as cast iron to
create a thin adhering layer that provides strong
adhesion and increases corrosion protection.

7. POWDER COATING
Powder coating is a metal finishing process that
involves the application of a dry powder rather
than a liquid to coat a metal product. A variety
of ingredients, including pigments, curatives,
flow modifiers, leveling agents, and other
additives, are combined to create the dry powder
coating during the powder coating process.

REMOVING AND RESHAPING METAL FINISHING PROCESSES
Metal finishing techniques such as removing and
reshaping are used to change the surface of a
part or product to achieve the desired finish by
removing or reshaping it. When the end user wants
a polished, reshaped, abrasive, or aesthetically
pleasing finished part or product, these metal
finishing processes are used
