What Is the Emissivity of Tungsten Carbide?

Click For Summary
SUMMARY

The emissivity of tungsten carbide (WC) is approximately 0.85, as referenced in a paper linked by a forum user. This value is crucial for accurate temperature analysis when using a handheld infrared camera during machining processes. The discussion highlights the importance of inputting the correct emissivity value to ensure precise temperature readings while working with cutting tools on a lathe.

Hi,
For the purpose of my FYP I am carrying out temperature analysis on a single point cutting tool while machining on a lathe. I am using a handheld infrared camera to determine this.

In order to carry this out accurately the emissivity of the material must be inputted to the device as a parameter...something I cannot find!

Would anyone out there know the emissivity of tungsten carbide or perhaps even an approximate value?

Regards,
