Sprayed Coatings

The microstructure of spray coatings using a newly developed thermal spray technique, High Velocity Arc Spray (HVAS), was studied and compared with those of regular arc sprayed coatings. The mechanical and wear properties of HVAS coatings were also investigated. The test results showed that HVAS coatings had better mechanical properties than those of regular arc sprayed coatings. The bonding strength of HVAS Al and 3Cr13 coatings was increased by 114 percent and 51.8 percent; the relative wear resistance of HVAS coatings was about twice that of regular arc sprayed coatings. The difference of microstructure and tribological properties between HVAS and regular arc sprayed coatings was discussed. [S0742-4787(00)00203-4]

The Galaxy

It is now possible to determine proper motions of high-velocity objects in such a way as to obtain with some accuracy the velocity vector relevant to the Sun. If a potential field of the Galaxy is assumed, one can compute an actual orbit. A determination of the velocity of the globular clusterωCentauri has recently been completed at Greenwich, and it is found that the orbit is strongly retrograde in the Galaxy. Similar calculations may be made, though with less certainty, in the case of RR Lyrae variable stars.

Relativistic Particles

The efficiency of the transfer of energy from supernovae into interstellar cloud motions is investigated. A lower limit of about 0·002 is obtained, but values near 0·01 are more likely. Taking all uncertainties in the theory and observations into account, the energy per supernova, in the form of relativistic particles or high-velocity matter, needed to maintain the random motions in the interstellar gas is estimated as 1051·4±1ergs.
