Question

A few years ago, most manufacturers were not likely to acknowledge that impregnation was a reliable way to seal porous cast or powder-metallurgyparts.

Answer 1

Несколько лет назад большинство производителей вряд ли бы признали, что пропитка является надежным способом герметизации литых пористых деталей, изготовленных методом порошковой металлургии.

Answer 2

As of my last update in September 2021, I don't have access to real-time data, so I can't provide the current status or trends in the manufacturing industry. However, I can speak to the general trends up to that point.

In the past, impregnation was not always considered a reliable method for sealing porous cast or powder-metallurgy parts. Impregnation is a process where a liquid sealant is introduced into the porosity of a material to fill and close off the voids, making it less permeable to gases or liquids. While the process has been used for decades and can be effective when done correctly, there were some challenges and misconceptions associated with it.

One of the main issues was ensuring that the impregnation process was done thoroughly and consistently. Properly sealing porous parts requires attention to detail, and if not done correctly, the impregnation might not be effective, leading to potential quality issues. As a result, some manufacturers may have been hesitant to acknowledge impregnation as a reliable solution, especially if they had encountered difficulties or inconsistencies in the past.

However, the manufacturing industry is continually evolving, and technologies and processes are constantly being improved. Over time, advancements in materials, equipment, and quality control have likely addressed some of the concerns related to impregnation. As a result, the perception and acceptance of impregnation as a reliable sealing method may have changed in recent years.

It's always best to consult up-to-date sources and industry experts to understand the current trends and practices in the manufacturing sector. If you're specifically interested in impregnation as a sealing method, reaching out to manufacturers or experts in the field can provide you with the most current and accurate information.
