Title: Calcium phosphate cover material
Inventor: IRIE HIROYUKI
IPC: A61C8/00
Filed: 1990-06-05
Abstract: PURPOSE:To cover a titanium-based metal with a calcium phosphate-based bioactive layer, by a method wherein a glass powder yet to undergo a crystallization processing is attached to a titanium-based metal, then bonded thereon by a thermal treatment, and a calcium phosphate layer is deposited. CONSTITUTION:For example, in pure titanium, a transition temperature from the alpha phase to the beta phase is near 880 deg.C and so, according to the title purpose, a glass permissible to a crystallization processing below 850 deg.C is adjusted. As deposited crystal, beta-calcium phosphate or apatite hydroxide is used. Viewed from composition considering affinity to a base material, when CaO and P2O5 are used as main components, TiO2 is added thereto also as crystallizer of the crystal. Moreover, Al2O3 and SiO2 are added and alkali components also, as required, to make said adjustment so that the desired crystal can be deposited while the mixture becomes easy to vitrify from the composition. A crystal glass thus obtained is used to be applied on or attached to a titanium base material by coating, spraying or the like, and then, bonded and attached on the base material by a heat treatment to form a calcium phosphate layer by deposition.

Further, a backfire prevention plate 5, which prevents the backfire from spreading upstream, is arranged below the flame hole plate 3. When the ignition is tired, at first the flames are formed at the upper part of the passage holes 4 of the flame hole plate 3 and then, after one or two minutes, the combustion spreads to the surface carried with catalyst of the flame hole plate 3 and turns to be in the catalytic combustion state to generate the flameless combustion and to bring the flame hole plate 3 into red-hot state. As a result, the material to be heated is mainly heated by the radiant heat from the red-hot plate 3 and no abnormality especially occurs even when the material to be heated is brought remarkably close to the flame hole plate 3.
