Diffusion bonding definition
Diffusion bonding. (1 2 9) means a solid state joining of at least two separate pieces of metals into a single piece with a joint strength equivalent to that of the weakest material, wherein the principal mechanism is interdiffusion of atoms across the interface.
Diffusion bonding. (1 2 9) means a solid state molecular joining of at least two separate metals into a single piece with a joint strength equivalent to that of the weakest material.
Diffusion bonding. (Categories 1, 2, 9) means a solid state joining of at least two separate pieces of metals into a single piece with a joint strength equivalent to that of the weakest material, wherein the principal mechanism is interdiffusion of atoms across the interface; “digital computer” (Categories 4, 5) means equipment which can, in the form of one or more discrete variables, perform all of the following: a. Accept data; b. Store data or instructions in fixed or alterable (writable) storage devices; c. Process data by means of a stored sequence of instructions which is modifiable; and d. Provide output of data; NoteModifications of a stored sequence of instructions include replacement of fixed storage devices, but not a physical change in wiring or inter-connections. “digital transfer rate” (Category 5) means the total bit rate of the information that is directly transferred on any type of medium; N.B.See also “total digital transfer rate”. “direct-acting hydraulic pressing” (Category 2) means a deformation process which uses a fluid-filled flexible bladder in direct contact with the workpiece; “drift rate” (gyro) (Category 7) means the component of gyro output that is functionally independent of input rotation. It is expressed as an angular rate. (IEEE STD 528-2001); “effective gramme” (Categories 0, 1) of “special fissile material” means: a. For plutonium isotopes and uranium-233, the isotope weight in grammes; b. For uranium enriched 1 per cent or greater in the isotope uranium- 235, the element weight in grammes multiplied by the square of its enrichment expressed as a decimal weight fraction; c. For uranium enriched below 1 per cent in the isotope uranium-235, the element weight in grammes multiplied by 0.0001;
Examples of Diffusion bonding in a sentence
Diffusion bonding in aluminum is difficult to achieve without taking measures to prevent oxide layer formation such as processing in either a vacuum or a reducing atmosphere or by eliminating the oxide in-process by using an alkali flux to clean the surfaces.
Diffusion bonding occurs when two objects are heated under pressure and diffusion takes place across the interface.
