ESPON-ACR3 Anti-Scale Protective Coating for Industrial Use

ESPON-ACR3 Protective Coating for heat retention in titanium billets and reducing alpha-case formation.
Much caution must be taken to assure that forging is carried out at a precisely controlled temperature while heating titanium, Inconel, and other extremely critical super alloys. Heat is quickly lost from heated billets during titanium forging, which makes forging and any subsequent processing extremely challenging. Titanium billets that lose heat may be rejected because they don't meet the necessary specifications. Furthermore, similar to oxidation and decarburisation in steels, titanium is prone to formation of alpha-case on the surface during heating at high temperatures. This causes rejection of parts during final testing. Hence, after the pieces are created, the alpha case that is formed on titanium needs to be eliminated by grinding. Alpha case removal is a tedious process as hard titanium is not easily machinable. Therefore, titanium needs to be coated with ESPON-ACR3 before heating. As a result, heat is retained in heated titanium billets, allowing for planned forging or other processing. The use of ESPON-ACR3 protective coating significantly lowers the production of alpha cases on titanium. ESPON-ACR3 protective coating can be applied by brushing, spraying or dipping. This coating has no effect on the characteristics, heating time or temperature after heating of coated parts. ESPON-ACR3 is non-flammable and non-hazardous.

Benefits of ESPON-ACR3 Protective Coating on Titanium:

1. Maintains heat in heated titanium billets

2. Considerably reduces formation of alpha case on heated titanium parts

3. Enhances yield. 

4. Conserves expensive titanium material from loss due to alpha case formation

5. ESPON-ACR3 can be used to protect titanium at heating temperatures up to 1260 deg °C.
