High Precision Aluminum Regulator Home Coffee Grinder: How does a stainless steel base improve blade durability?

Regarding the 64mm stainless steel titanium-plated blade of this High Precision Aluminum Regulator Home Coffee Grinder, the material selection plays an important role in maintaining sharpness and durability. Stainless steel is an alloy material mainly composed of elements such as iron, chromium, nickel, and sometimes contains small amounts of carbon, silicon, manganese and other elements. Its internal atoms are closely arranged to form a stable crystal structure, which gives stainless steel high strength, high hardness and good corrosion resistance.
The high hardness of stainless steel means that when subjected to external forces, such as pressure and friction when grinding coffee beans, its surface is not easy to scratch or wear. At the same time, stainless steel also has high yield strength and tensile strength, and can withstand large deformation without breaking.
The corrosion resistance of stainless steel is mainly due to the chromium oxide film on its surface. This film can prevent oxygen, moisture and other corrosive substances in the air from reacting with the iron atoms inside the stainless steel, thereby avoiding rust and corrosion. During the process of grinding coffee beans, this film can also effectively resist the corrosion risk caused by oil, moisture and other components in the coffee beans.
Titanium plating is a surface treatment technology that improves the surface properties of a metal by depositing one or more layers of metal or non-metallic films on the surface of the metal. Plating a layer of titanium film on the surface of a stainless steel blade can significantly improve the wear resistance, corrosion resistance and hardness of the blade.
The titanium plating process usually includes three steps: pretreatment, electroplating and post-treatment. The pretreatment stage is mainly to clean the surface of the blade and remove impurities such as oil and oxide layer to ensure good bonding between the coating and the substrate. The electroplating stage is to deposit titanium ions on the surface of the blade under the action of an electric field to form a uniform and dense titanium film. The post-treatment stage is to passivate and polish the coating to improve its corrosion resistance and aesthetics.
The surface hardness of the blade after titanium plating is significantly improved, which can more effectively resist the friction and wear generated during the grinding process. At the same time, the smooth surface of titanium helps to reduce the friction resistance between the coffee beans, thereby improving the grinding efficiency and maintaining the sharpness of the blade. In addition, titanium also has good corrosion resistance and biocompatibility, making titanium-plated blades less susceptible to corrosion and contamination during long-term use.
