However, with technological advancements and research in the field, impregnation has become a widely accepted and proven method for sealing porosity in various metal components. The process involves filling the pores with a sealing material, typically a resin or polymer, to create a impermeable barrier that prevents leakage and improves the mechanical properties of the part.

Manufacturers have started to recognize the benefits of impregnation, including improved part performance, enhanced corrosion resistance, and extended part life. Additionally, impregnation can be cost-effective compared to alternative methods such as welding or coating, making it a preferred choice for many applications.

Overall, the acceptance of impregnation as a reliable sealing method has grown in recent years, and it has become an essential part of the manufacturing process for many industries. As technology continues to advance, impregnation will likely continue to be a preferred method for sealing porous metal parts.
