Surface Treatment and Structural Design for Machined Mechanical Components
Release Date:
2024-02-27
A method in which an oxide film containing metal cations is applied to the surface of a workpiece and, under appropriate conditions, oxidized to form a colored metallic layer. Metal anodizing processes include electrochemical oxidation, chemical oxidation, and plasma oxidation, among others.
There are four types of surface treatments for machined mechanical components:
1. Anodizing:
A method in which an oxide film containing metal cations is applied to the surface of a workpiece and, under appropriate conditions, oxidized to form a colored metallic layer. Metal anodizing processes include electrolytic oxidation, chemical oxidation, and plasma oxidation, among others.
2. Electroplating:
A process in which a metallic coating is deposited on the surface of a metal or alloy by chemical or electrochemical means. Electroplating is a widely used and heavily applied surface-finishing technique in hardware manufacturing. Today, electroplated products encompass more than thirty different types, with many reaching world-class standards, such as nickel plating, chromium plating, copper plating, and gold plating.
3. Chemical Polishing:
A machining process in which the workpiece surface undergoes chemical or electrochemical changes under the action of abrasives, chemical solvents, and other agents, thereby achieving the desired objective.
4. Sandblasting:
A machining process that uses mechanical methods to impart a fine, sand-like surface roughness to workpieces, thereby enhancing their surface friction characteristics.
During the structural design of machined mechanical components, the following aspects should be taken into consideration:
1. Weight of components:
During the product design phase of mechanical component machining, it is necessary to analyze and optimize the components based on specific conditions in order to minimize their weight as much as possible.
2. Material Selection for Mechanical Components:
During product structural design, it is necessary to select appropriate materials based on the product’s functional requirements and cost constraints.
Characteristics of machining mechanical components:
1. Quality Stability:
Because mechanical components are often made from various metals, significant deformation can occur during machining, making it difficult to reliably assess the quality of metal hardware components after manufacturing.
