The oven is in order to obtain sinteredlayer, sintering layer directly affects the service life of the furnace, the furnace chamber was built, immediately before the baking oven;
烘炉是为了获得烧结层的过程，烧结层的好坏直接影响到了炉子的使用寿命，炉腔筑好后，应立即进行烘炉；

Coated by the mixed powders of neutro-glass and A-W bioactive glass ceramics on TC4 matrix and presintered to form a transition layer, the samples then were coated with A-W powders and sintered again.
Obviously, the composition, structure and properties of the intermediate layer play an important role in some main properties of the sintered polycrystalline diamond.
