Benefits of technology

This patented process allows for better quality coatings on metallic surfaces that are used in various industries such as construction or manufacturing processes where they may be exposed during use without rustling over time due to exposure to environmental factors like rainwater or other liquids containing chlorine gas (Cl2). By doing this, these protective layers can prevent damage from corrosives caused by harmful substances found inside buildings' structures.

Problems solved by technology

This patented technical problem addressed by this patents relates to reducing damage caused during thermal spraying processes used for protective layers onto metals such as steel sheets. Current methods are often poorly understood due to their lack of uniformity across different areas of the substrate being treated. There needs an enhancement from current solutions with better results than traditional techniques alone.
