- NiCrAl metal powder is coated by the spray method.
- a pre-press is applied to the formed metal product stack such that about 20% of the initial thickness of the metal foam stack is pressed using a press machine.
- the pressure applied at the prepress is removed, and again the metal with constant weight
- the plate (molybdenum or ceramic block) was placed on a metal stack and pressure was applied by the method, while heat treatment was performed at 1280 ° C., thereby producing a metal foam stack having a length of about 280 mm in width and length, respectively.
- Example 1 a metal product stack is manufactured in the same manner as in Example 1 except that no pre-pressure is applied.
- Example 1 a metal product stack is manufactured in the same manner as in Example 1 except that the heat treatment is performed without applying pressure through the loading member.
- Each of the metal foam stacks having a width of 280 mm wide prepared in Example 1 and Comparative Examples 1 to 2 was cut by using a band saw having a length of about 40 mm wide. In this way, 49 samples are prepared. Each cut sample is measured approximately 49 times in tensile strength using a UTM universal test ing machine and the average value is the adhesive strength.
- Example 1 including applying a pre-pressure or pressing through the loading member shows an excellent average tensile strength compared to Comparative Examples 1 and 2.
