The Tru Temp satin black magnetite coating is just 0.5 microns thick, with no effect on material hardness or tensile strength.
Couplings used in servomotors and other high-speed automation applications take on a strong, protective and attractive finish when treated with Tru Temp low-temperature, nonpolluting black oxide from Birchwood Casey Metal Finishes.
The Tru Temp process forms a nondimensional, deep black finish with long-term corrosion resistance that suits couplings, torque limiters, gears, shafts and similar power transmission devices.
The Tru Temp finish also prevents galling on thread surfaces and other critical part features.
The satin black magnetite coating is just 0.5 microns thick, with no effect on material hardness or tensile strength.
The finish withstands up 100-200 hours of neutral salt spray (ASTM B 117) or several hundred hours of humidity (ASTM D 1748).
This high level of corrosion protection is important for both part storage and shipment in corrosive atmospheres including ocean shipment.
The Tru Temp solution operates at 93C and uses mild alkaline chemistry that does not embrittle steel components.
Consequently, the Tru Temp system is a very safe and effective option for high-quality, in-house black oxiding that improves quality with a short turnaround time.
Conventional 143C hot oxide processes are dangerous to operate because of their tendency for splattering and boilover.
Coupling manufacturers using the Tru Temp process report part finishing costs such as coupling hubs were reduced from 20 to 4 US cents each.
Turnaround time with an in-house system went from five days to same-day.
Small parts can be processed in bulk loads, with larger parts finished on racks.
Most existing tank lines can be retrofitted for Tru Temp at a low cost.
The process can be automated, at low cost, through the use of a CNC programmable hoist system.
Tru Temp contains no EPA-regulated chemicals, so there is usually no need for waste treatment equipment.
In most areas, the rinse waters are sewerable as nonhazardous discharge.
This simplifies installation and minimises the capital investment needed to set up the process line.
