Preoxidation and Postoxidation Furnace
Preoxidation and postoxidation furnaces are crucial for the thermal treatment of various materials such as metals, ceramics, and composites. The process involves heating the material to high temperatures in the presence of oxygen, which leads to the formation of an oxide layer on the surface. The oxide layer formed in this process enhances the material's resistance to wear, oxidation, and corrosion.
Preoxidation furnace refers to the process of creating the oxide layer before applying any coating or plating to the material. This layer acts as a base for the subsequent layers and ensures the adhesion of the coating to the surface. On the other hand, postoxidation furnace is used after the coating or plating process to further enhance the properties of the material.
Function
The chamber is a climatic chamber specifically designed to perform carbonation tests on concrete samples.
Configuration
Preoxidation and postoxidation furnaces are available in both batch and continuous configurations.
Features
Features can vary depending on the model and manufacturer, but common features include programmable temperature controllers, automatic shut-off systems, and safety interlocks.
Temperature Range
The temperature range can vary depending on the specific process and material being treated.
Heating Rate
The heating rate of the furnace is adjustable, with options for ramp and soak programming as per the process requirement.
