...Abstract Abstract The silver layer on a thrust bearing face experienced electrostatic discharge attack (the bombardment of an in-line series of individual sparks onto the soft bearing face), which destroyed the integrity of the bearing surface. The electrical attack appeared as scratches...

... begins with electron bombardment of the sample material, causing an atom to eject an inner-shell electron and thus forming a vacancy. A second electron from a higher shell fills this inner-shell vacancy in an energy-gain process. This energy can then cause the ejection of a third electron, referred...

.... Quantification is possible with the use of elemental sensitivity factors ( Ref 3 ) that have been determined empirically and found to be in agreement with the current theoretical models for quantification of XPS data. If the sample is insulating, x-ray bombardment can create a positive-charge buildup...

... mercury peak. This made detection of mercury very difficult. Only after extensive and repeated EDS examination was sufficient evidence to confirm mercury contamination was collected. The high vacuum environment in the SEM combined with electron bombardment during examination may vaporize most...

... analysis on the fracture surface was carried out with a secondary ion mass spectrometer (SIMS). For this analysis, nitrogen gas ions ( N 2 + ) accelerated to 20 kV were bombarded on the fracture surface. Fig. 8 shows the effect of molybdenum content on the depth profile of sulfur ion ( 32 S...

... of parts per million (ppm). This technique is extremely sensitive and is even capable of detecting hydrogen. In SIMS analysis, the sample surface is bombarded by primary ions, which undergo multiple atomic collisions directly beneath the surface. This causes infrequent ejection of various atomic species...

In sputter coating, the sample is placed in a vacuum chamber beneath a metallic target, usually of gold or gold-platinum. After a vacuum is achieved, a partial pressure of argon is introduced...

... concentrated as the water evaporates under the influence of the dry region. The damage caused by the long term bombardment of liquid droplets does not typically proceed at a uniform rate even if the liquid impingement is uniform with time [ 17 ]. There is an initial phase during which there is usually some...

Although no deposition may occur, abrasion can take place when refractory or ceramic linings are bombarded by dusts. The extent of abrasive wear depends on the impinging particle size, shape...
