TTi(Thermal Toughness Index)

TTi(Thermal Toughness Index)

TTi is the index of heat resistance for superabrasives. The thermal stability of diamond grits is of particular importance in processing since it directly influences on the processing quality, tools life, production efficiency and cost.

Testing method: Putting the samples into the high-temperature sintering furnace by heating in 1100℃ for 10 minutes, then let the samples to do the TI testing, the percentage value is TTI value.
