Release Time : 2025-12-15
The bonding process between the titanium layer and the inner layer of a multifunctional constant temperature titanium pot is one of the core technologies determining its performance. This process not only needs to ensure a strong bond between the titanium layer and the inner layer material, but also needs to consider thermal conductivity, wear resistance, and non-stick properties to meet the diverse needs of cooking. Traditional titanium pots often suffer from insufficient bonding between the titanium layer and the substrate, leading to problems such as titanium layer detachment and uneven heat conduction during use. The multifunctional constant temperature titanium pot, through innovative processes, achieves deep integration of the titanium layer and the inner layer, thereby improving overall performance.
The bonding process between the titanium layer and the inner layer of a multifunctional constant temperature titanium pot typically employs composite coating technology. This technology creates a complementary structure through the superposition and fusion of multiple materials. For example, some high-end products first spray a titanium-copper-iron composite coating onto the inner surface of the pot base, utilizing the corrosion resistance of titanium, the thermal conductivity of copper, and the strength of iron to form a basic functional layer; subsequently, a titanium-silicon hydrophobic coating is sprayed onto the surface of the titanium-copper-iron composite coating, using the hydrophobic properties of silicon to enhance the non-stick properties of the cookware. This multi-layered composite structure ensures the stability of the titanium layer while enhancing the overall performance of the cookware through the synergistic effect of other materials.
In terms of specific process implementation, cold spraying technology is key to the bonding between the titanium layer and the inner layer of the multifunctional constant temperature titanium pot. Cold spraying is a technique that uses a high-pressure gas flow to accelerate metal powder to supersonic speeds and impact the substrate surface to form a coating. Compared to traditional hot spraying, cold spraying does not require heating the metal powder to a molten state, thus avoiding oxidation and performance degradation of metals such as titanium at high temperatures. In the production of the multifunctional constant temperature titanium pot, cold spraying technology is used to uniformly spray titanium-copper-iron powder and titanium-silicon powder onto the inner surface of the pot substrate, forming a dense, low-porosity coating. This coating not only has strong adhesion to the substrate but also effectively resists wear and corrosion during cooking.
In addition to cold spraying technology, micro-forging processes also play an important role in the bonding between the titanium layer and the inner layer of the multifunctional constant temperature titanium pot. Micro-forging, achieved by applying a slight pressure to the sprayed coating using a hydraulic press, eliminates porosity and defects, further enhancing its density and adhesion. This process also smooths the coating surface, reducing friction between food and cookware during cooking and thus improving non-stick properties.
The choice of materials is equally crucial in the bonding process between the titanium layer and the inner layer. Multifunctional constant temperature titanium pots typically use high-purity titanium as the inner layer material to ensure its chemical stability and prevent the leaching of heavy metals. Furthermore, to improve the cookware's thermal conductivity and durability, the inner titanium layer is often combined with materials such as aluminum and stainless steel. For example, some products employ a three-layer composite structure of "pure titanium-aluminum-stainless steel," where the aluminum layer acts as a heat-conducting bridge, quickly and evenly transferring heat throughout the pot; the stainless steel layer provides structural support and wear-resistant protection. This multi-layer composite structure retains the health benefits of titanium while enhancing the overall performance of the cookware through the complementarity of other materials.
The bonding process between the titanium layer and the inner layer of the multifunctional constant temperature titanium pot also emphasizes meticulous attention to detail. For example, before the coating is applied, the surface of the pot substrate undergoes rigorous cleaning and pretreatment to ensure the adhesion between the coating and the substrate. After the coating is applied, the cookware undergoes sanding, cleaning, and drying processes to further improve surface quality and hygiene standards. These detailed treatments not only enhance the aesthetics of the cookware but also extend its service life.
