摘要： A method of and apparatus for the detection of pitting corrosion, in which simultaneous measurements of the rate of loss of material from a body under test are made by means of changes in the resistance of the body and thin layer activation analysis. If the body is corroding uniformly, the rate of loss of material as measured by each technique is the same; if pitting corrosion is occuring, then the two measured rates of loss of material are different.

摘要： A process for measuring the service life of heat shields on reentry spacecraft after each flight is disclosed. A low electronenergy level, beta emitting, isotope, having a reasonably long half-life, preferably promethium-147, is uniformly dispersed throughout a refractory heat shield coating. The beta particle emission level at the coating surface is measured to provide a base reading. After each space flight, the beta emission level at the coating surface is again measured, such as by autoradiography or with a Geiger-Muller counter. Erosion, abrasive wear, spalling or other damage is detected and measured to determine whether additional flights can be made without re-coating.

摘要： A method and apparatus are described for quantative determination of the level of spalling of a protective surface coating as a result of repetitive heating and cooling. The method comprises introducing at least one radionuclide into the protective coating of an article (16), alternately heating and cooling the article (16) for a predetermined number of heating and cooling cycles, collecting the spalled particles (10) and measuring the radioactivity thereof. The apparatus comprises a chamber (2) for receiving the coated article, means (4) for heating the chamber (2) or the article (16) and a spall collector (8). The spall collector (8) is characterized in having means for immobilizing any spalled coating particles (10) and in being so adapted that the level of radioactivity of any spalled particles can be measured by a η-spectrometer.

摘要： A test fixture for determining circumferential shear properties of an arcuate test specimen may include an outer fixture and an inner fixture. The outer fixture may be coupled to an outer side of the test specimen, and may be rotatably mounted on a central pin and may include a rocker arm. The inner fixture may be coupled to an inner side of the test specimen, and may be rotatably mounted on the central pin and may include a load arm extending in a direction opposite the rocker arm. The inner fixture and the outer fixture may be configured such that application of a test load to the rocker arm and the load arm causes rotation thereof about the central pin producing circumferential movement of the inner side relative to the outer side and inducing a circumferential shear load in the test specimen.

摘要： A method of monitoring thinning of pipe walls in a piping system including selecting locations to be monitored, normally those pipes particularly susceptible to thinning from erosion/corrosion, boring holes in the outer surfaces of the pipes at the selected locations to depths greater than the thickness at which the pipes will rupture to leave predetermined residual wall thicknesses between the ends of the holes and the inner surfaces of the pipe walls, inserting tracer materials in the holes to be released in the pipes when pipe wall thinning exceeds the residual wall thicknesses of the holes, monitoring fluid flow through the piping system to sense the presence of tracer materials in the fluid, and determining the location of the hole from which a sensed tracer material was released to permit pipe wall thinning to be determined prior to pipe rupture allowing repair or replacement during scheduled downtime of the piping system. Preferably, a series of spaced holes are bored to differing depths at each location such that, knowing the difference in depth and thus residual thickness between holes and the time period between detection of tracer materials from each hole, the rate of pipe wall thinning can be determined, and the period of time in which the pipe can be safely repaired can be calculated.
