When observed from the graph shows a comparison of the sample, it was found that, the thermal annealing furnace for 1 h., the amount of titanium is higher than the hot air blow for 10 minutes , maybe because the oven is controlled amount of oxygen.
Less than blowing hot air In normal weather conditions, which do not have a closed system like the heating oven. It has a high percentage of oxygen and results in a lower percentage of titanium heating stove.
