App to Improve and Map Passivation Processes

Walter Surface Technologies offers the SURFOX Smart Passivation Tester, a passivation tool and a component of its SURFOX electrochemical cleaning system, to analyze passivation levels in stainless steel. The tool includes a cloud-based app that can be managed via smartphone, which measures chemical levels to determine the degree of passivation in which the stainless steel item (e.g., in mixing tanks or drums) is currently contained.

Passivation is the process by which chemical reactions cause stainless steel to reach a more protected state where it is less vulnerable to corrosion. It occurs when the chromium contained in stainless steel comes in contact with oxygen, forming a passive chromium oxide layer that protects a stainless steel surface. Once the passivation process is completed, materials are less affected by environmental factors.

The SURFOX passivation app allows machinists to capture data, which is stored via the cloud, and utilize telemetry to analyze the changing chemical levels during this passivation process. Technicians can then map the oxidation process and track the progression of the passivation state in the stainless steel item and identify if the piece has been fully passivated to avoid rust and corrosion.

"The concept of leveraging technology, cloud-based platforms and mobile apps to support production in the metal equipment industry is still emerging, yet it is a way for machine shops and fabricators to differentiate themselves, offering more efficient and accurate assessments of how their metal equipment will endure over time," said Jonathan Douville, Product Manager at Walter Surface Technologies. "We are looking to help our customers use these new technologies to become more competitive, especially smaller machine shops who are competing for business with larger companies that are in possession of greater resources. The more we can increase awareness of how technology can help deliver an edge to these shops, the sooner we can speed adoption of these enhanced processes in the market."
