PRODUCT SHOWCASE: Gear Break-In Lubricity And Rust Protection Achieved With Tru Temp Black Oxide

Gear component manufacturers can easily achieve break-in lubricity, robust corrosion protection, and galling resistance on critical components. Birchwood Technologies’ Tru Temp® low temp black oxide process meets demanding finishing requirements while creating a non-dimensional finish, maintaining the same material hardness and load-bearing properties.

The Tru Temp blackening line operates at 200 degrees and forms a satin black magnetite finish that protects critical surfaces in storage, shipment, and startup, resists galling, and aids in break-in. The process takes just 30 minutes.

The Tru Temp finish is Mil Spec and RoHS compliant and withstands up to 120 hours of neutral salt spray or several hundred hours of humidity, verified by independent testing. The finish is 0.5 microns thick (20 millionths) crystalline structure that allows it to effectively hold a rust inhibitor and serves as a sacrificial barrier to provide break-in lubricity and galling resistance. Critical parts are protected for storage or overseas shipment.

Gear component manufacturers who have already installed a Tru Temp low-temperature black oxide system are seeing many benefits. The process can be installed in any plant setting, without endangering personnel or surrounding equipment. The operating solutions contain no EPA regulated chemicals; process rinse waters are normally sent to the sewer as non-hazardous discharge. Most process lines do not require waste treatment equipment.

Tru Temp process lines are available in any size to fit part size and production volume. Visit Birchwood Technologies’ website for details on 100-gallon and 40-gallon systems.
