In revision hip arthroplasty, bone loss can be compensated by impacting allograft material. Cleaning processes reduce the risk of bacterial and viral contamination. Cleaned allograft material was compared to native untreated allografts by using a uniaxial compression test. 30 measurements were performed for each group before and after compaction. Grain size distribution and weight loss were determined. A reduction in the amount of large bone fragments and a higher compaction rate were observed in the cleaned bone grafts. The cleaned bone chips presented with a better mechanical resistance to a

"electromagnetic field at the particl e has to be computed numerically. An example of such a computation using a program based on [49] is given in Fig. 4. But not only doe s the Mie theory describe an enhancement of the laser intensity in the particles' near field, it also predicts that for certain values of the size parameter nd/X (d denoting the particle diameter, À the laser wavelength) the enhancement should be particularly efficient, resulting in a resonant intensity enhancement, the so-called "Mie-resonances". 3.2.2. Near-field induced substrate damage When inspecting contaminated samples by scanning electron microscopy (SEM) or atomic force microscopy (AFM ) after DLC using ns laser pulses, the consequences of the field enhancement process became obvious: all over the cleaned areas w e found substrate damages localized exactly at the former particle positions [35, 37-39]. These damages manifested as melting pools or even holes in the surface, typical examples can be seen in Fig. 5. The consequences for the laser cleaning process are obvious. The intensity enhancement reduces the maximum laser fluence that can be applied in the process. Usually in laser cleaning studies [19, 31 ] the laser fluence corresponding to the melting threshold of a bare surface is taken as the damage threshold fluence. Our experiments show clearly that this is an inadequate definition. Instead one must take into account the enhanced laser fluence underneath the particles, as it will be discussed in Section 4. Fro m the obtained AFM images we were able to analyse in detail the surface profile at the damaged sites. Here we found that for high field enhancement factors the silicon substrate was not only molten , but that some material was even ablated (see Sec. 4). The momentum transfer to the particles during the ablation process significantly contributes to the cleanin g process and hence local substrate ablation." In Surface Contamination and Cleaning.

"of the spectral response, the integrated reflection-absorption intensity, of these samples are slightly greater than the intensity of the spectral response of the same samples measured via a 60 ° angle of incidence data (Figure 3). This behavior is expected due to the increase in reflection-absorption sensitivity with increasing angle o f incidence. Here, too, the average initial slope (and hence instrument sen-sitivity) is the same for both transverse and longitudinal orientations. The pronounced non-linearity in slope for the thickest films at 75° angle-of-incidence was unexpected. A n increasingly non-linear response may be observed for thicker absorbing films, and this effect will become more pronounced as the angle of incidence is also increased. The interpretation of the data implying that measurement of a thicker film, sampled at a steeper angle, generated the observed non-linearity in the data is not substantiated by th e calculated spectra for the pre-sent measurement conditions due to the small change from 60 to 75° in the angle of incidence. Furthermore, such a non-linear effect would be most pronounced for measurements on the smoothest substrat e (Figure 4, filled circles) where the ef-fective local orientation of the surface is most constant with respect to the illumi-nation beam. Instead of observing such non-linear behavior the measurements made on the smoothest surface are by far the most linear sample series for the 75° data . We attribute the pronounced non-linearity of the 75° data for the thickest draw-ing-agent films to the morphological characteristics of the material as deposited o n the aluminum test panel surface. As described above, the drawing-agent mate-rial is highly viscous and forms a visibly heterogeneous white film at l-|im thick-ness. Variations in the deposition process produce relatively thick local areas of drawing-agent film and result in accretion of solid residue along the polishing grooves and ridges of the aluminum substrate. Under these circumstances, illumi-natio n of the surface with the FTIR beam at an angle of 75° may result in shadow-ing by contaminant material on ridge structures for all except the smoothest (600 grit polish) surface. The 12-mm diameter focal area of the infrared beam is elon-gated by a factor o f four for this angle of incidence. In contrast, reflectance meas-urements at 60° result in only a factor of 2 elongation, and minimize the shadow-ing effect of thick films except for ridges on the roughest (80 grit polish) surfaces. This interpretation is substantiated by reflectance data for the second test set (lubricant material) as shown in Figure 5. FTIR reflectance measurements have been made at 75° angle-of-incidence for a test series similar to that of the draw-ing-agent set. An analysis of the C-H stretching frequencies shows a strikingly more linear dependence of instrument response with film thickness (with the ex-ception of a single point for one of the panels with a 220 grit surface finish). We believe that this is due to the more fluid characteristic of the lubricant material, which allows the deposited film to conform much more closely to the surface to-pography of the test coupons. This behavior may also account for the stronger de-pendence of the integrated intensity slope with surface roughness, when compared to the nearly constant results for the drawing-agent contaminant examined above."

Abstract This technical paper introduces a newly developed surface preparation process termed bristle blasting, which utilizes a specially designed rotary power tool for simultaneously removing corrosion and generating an anchor profile. The process derives its name from sharp, hardened bristle tips which, upon striking the corroded surface, immediately retract, thereby creating a micro-indentation that both removes corrosion and simultaneously exposes fresh subsurface material. Consequently, the repeated collision/retraction of bristle tips with the corroded surface leads to a surface cleanli

Abstract Aluminum finned copper-tube heat exchanger coils at an industrial facility experienced localized corrosion after a few months of operation. Initial testing indicated that the potential cause of corrosion was due to a process known as formicary corrosion. The source of the corrosion was investigated by performing air sampling of the location prior to and during the floor cleaning process as a way to determine whether the chemical cleaners used in the facility were potentially responsible for the accelerated corrosion. While some aggressive species were identified prior to the floor cle

Abstract As with many heat exchangers, nuclear steam generators are subject to the accumulation of corrosion product deposits on heated tube surfaces and other internal components on the secondary (shell) side. These deposits can have adverse effects on thermal efficiency, material integrity, and in some cases plant operability. Accordingly, plant operators routinely devote substantial resources to limiting the generation and accumulation of deposits, including periodic removal of deposits through various mechanical and chemical approaches. Since the 1980s, chemical cleaning processes with sol
