The samples were dried in an oven at 80 oC overnight. The samples were grinded into fine powder after drying using a ceramic mortar and pestle. Accurately 2.0g of each of the powdered samples were weighed in a porcelain crucible. The fine powdered samples in the crucibles were ignited in a muffle furnace at 600 for three (3) hours.

The nitridation was carried out under a pressure of 0.1 Torr and with a flow rate of 100 sccm of ultra-high purity N2 for 10 minutes. The degree of nitridation and the nitrogen incorporation mechanism were evaluated as a function of the RPS power (0.5, 1.0 and 1.5 kW) and the dielectric temperature (300, 400 and 500 °C).

The degradation is discussed and traced to a reaction between oxygen and/or oxides diffused into the copper alloy during fabrication processes and the hydrogen utilized as a brazing furnace atmosphere during the initial assembly operation on many of the combustors. The effects of the H2/O2 reaction within the copper alloy are described.

Strategies for efficient operation of furnaces using nitrogen

Optimum parameters for steady state operation are determined by (1) the type of atmosphere desired— nonoxidizing (but decarburizing), or neutral, (2) the necessity for maintaining a positive furnace pressure, and (3) the rate of air leakage into the furnace.

sintered under vacuum, argon, nitrogen, nitrogen/hydrogen gas mixtures. Only pure nitrogen is an active sintering atmosphere for aluminium, because it promotes shrinkage and sintered mechanical properties, as proved by bend test. A key feature in the use of nitrogen is the formation of aluminium (oxy)-nitrides.
