Why Do Dies Used To Make Gold Medals And Coins Undergo Processes Of Hardening By Vacuum?
The hardening by vacuum of dies used to strike gold medals and coins is done by subjecting them to high temperatures under controlled conditions in a chamber. Here's a brief overview of the dies for vacuum hardening.
When making dies that will be used to strike coins or other medals, it's important that they are free of residues or contamination.
Loading Vacuum Furnace
The dies are placed inside a vacuum furnace, which is a specialized heat-treating chamber that can create a vacuum environment.
Evacuation by Airplane
The vacuum chamber is made by removing air from the chamber and creating an environment controlled and free of oxygen. This is done to avoid the formation of oxidation and to guarantee uniform heat treatments.
Heating Phase
The furnace is then heated to the temperature required for the hardening of dies. The temperature range varies based on the materials used and the processing for hardening.
Soaking in High Temperatures
Die dies are kept at the elevated temperature for a specified time which allows the material to attain and keep the desired hardness and metallurgical structure.
Quenching (or cooling)
With the help of special techniques that allow dies to be quickly cooled down or quenched after the soaking process. This rapid cooling process locks in the desired strength and hardness in the material.
Tempering (Optional)Tempering (Optional)
In certain circumstances the process of tempering can occur as a result of hardening. Tempering is the process of heating dies to a lower temperature in order to relieve internal tensions and improve durability.
Quality Control and Inspection
To ensure that they meet hardness and strength requirements Die dies that have been hardened go through a thorough inspection and quality test.
Post-Treatment Handling-
Die dies are then polished or coated, and used to strike coins or medals.
The process of vacuum hardening enhances the strength, durability of the dies, their wear resistance and the life of the dies used to create gold coins or medals. In ensuring a safe and contaminant-free environment the process offers a consistent and reliable way to make the dies harder.

What Are The Various Ways In Which Gold Coins Or Medals Are Coated To Protect Them?
There are many reasons why gold coins and medals can be coated. They can be used for the protection of your investment, enhancement to aesthetics or achieving specific effects. Here are different coating processes employed to protect your precious items. Coatings-
Clear Protective Film (Varies). This clear protective film, that may include lacquer and a polymer, helps protect the surface of the coin from oxidation. This coating protects and preserves the original look of the coin or medal.
Enhancement of Appearance
Gold plating (or gold plating) A thin layer or gold can be applied to the surface of gold coins or medals. This enhances the appearance of the medal or coin and gives it a more shiny and luxurious finish.
Aesthetic Effects
Antique or Patina Finishes- Chemical treatments or special coatings are applied to create an antique or patina finish. This process artificially age the surface and creates an aged, oxidized appearance.
Coloring and Colorization Certain areas of a medal or coins are colored with specific coatings or enamels. This is done to emphasize certain design elements, add interest, or to create visual interest.
Anti-Tarnish Coatings-
Anti-Tarnish Coatings and Solutions To coins or medals that have intricate designs or surfaces that are susceptible to tarnishing, anti-tarnish coats or solutions may be applied. The coatings protect the metal's surface from oxidizing or discoloring over time.
Specialized Coatings or Authentication for Security-
UV-Reactive Coatings or Luminescent Coatings - Some coins and medals could contain special coatings that respond to UV light. This exposes secret or encrypted parts for security or authentication reasons.
Selective Coatings for Contrast-
Selective Coating Removing - Sometimes the coating is removed selectively from particular areas of a coin or medal to provide contrast between polished and coated surfaces. This accentuates design aspects.
Each process has a specific objective, like to improve the appearance of the metal or appearance of metal, enhance protection, increase security, or produce certain aesthetic effects. The coatings be a significant influence on the durability and aesthetic appeal of gold-plated coins and medals. They also increase their value.
