Title: Melt nitriding method for aluminum and aluminum alloy
Inventor: YAMADA TOSHIHIRO
IPC: C23C26/00
Filed: 1979-08-08
Abstract: PURPOSE:To give aluminum or aluminum alloy excellent wear resistance, by keeping the aluminum or aluminum alloy in molten state by an arc heat source in an atmosphere of inert gas and ammonia, then by cooling it slowly. CONSTITUTION:Aluminum or its alloy is kept in molten state by an arc heat source in mixed gas atmosphere composed of ammonia and inert gas such as argon, helium etc. and is cooled slowly. Ratio of ammonia to inert gas is 10-20%. The time for keeping Al or Al alloy in molten state is about 30-90sec. For example, aluminum 1 and tungsten 3 are used as electrodes. A mixed gas consisting of 95% argon and 5% ammonia gas is fed into a torch 2 through a gas pipe 4. An arc is generated between both electrodes 1, 3 by an electric power source 55 to form a molten pool 7. The aluminum or its alloy is kept in molten state for 60sec, finally it is cooled slowly. Hereby AlN layer is formed uniformly in the surface layer, hence treated material attains wear resistance.

Abstract: PURPOSE: Fruits or vegetables are dipped in a sugar solution, taken out of the solution and frozen and the operations are repeated in turn in higher concentration solutions to produce candied fruits, thus permitting the production of high-quality candied fruits without deformation in a short time.  
     CONSTITUTION: Fruits or vegetables are subjected to pretreatments such as washing, peeling, blanching or bleaching. Then, they are subjected to freezing to form fine ice crystals in the tissues and dipped in a 20W40wt% sucrose solution so as to moderate the damages caused by freezing until the concentration of sucrose becomes 15W40wt% in the tissues. The operation of dipping in a low-concentration sucrose solution can be eliminated, when a material that have already been treated with an appropriate sucrose solution such as canned fruit is used, while it will take as long as 48hr, when carrots or burdocks are employed. The starting material treated with a low-concentration sucrose solution is taken out and frozen by placing it under a condition of lower than -12°C for 2W8hr, then dipped in a higher-concentration sucrose solution than that of the pretreating solution. In turn, the dipping operation is repeated using higher and higher concentration sucrose solutions to make the title candied fruits.
