TRU TEMP 2nd GEN Black Oxide

Oct. 21, 2021
Birchwood Technologies' TRU TEMP 2nd GEN Black Oxide is non-dimensional at 1 micron thick.

TRU TEMP 2nd GEN Black Oxide greatly expands on the predecessor finish by expanding into finishing a wider range of ferrous metals including iron, steel, tool steels, and most stainless steels, all with one formulation.

 

It generates a darker and cleaner black oxide finish on an expanded range of high-alloy and high-strength steels and iron. The magnetite finish is non-dimensional at 1 micron thick and ideal for machined components, non-machined components, powdered metals, MIM parts, tooling, gears, sucker rods, and more.

 

Operating at the optimum temperature range of 200° to 210°F (93.3 to 98.9°C), the black oxide makes it easy to use in-house and operator friendly. The chemistry is easy to manage and contains no EPA regulated metals, so rinse waters are generally sewerable by neutralizing the pH with a typical discharge range of pH 7-11. Additionally, reaching this pH range takes only 20% of the acid than other processes.

 

Additional features include protecting critical surfaces in storage, shipment, and startup while resisting galling, aiding with break-in lubricity, and no salt leaching problems. Plus, the process can be designed around several factors including: mix of alloys, hardness and reactivity, condition of the surface prior to blackening, parts handling employed, and the final finish requirement in terms of appearance, gloss, and corrosion resistance.

 

TRU TEMP 2nd GEN finish makes it easy and fast to supply customers just-in-time requirements. By using an in-house finishing system, a company can achieve cycle time reductions, inventory reductions, and overall process improvements.
