ABSTRACT:
The invention relates to a method for preparation of test bodies for analysis of porous, preferably thermally sprayed, surface layers, which are incorporated by casting in plastic. The method according to the invention is carried out by placing one or more test pieces of the surface layer in a mold introduced into a vacuum chamber, the pressure of which is lowered, pouring a ready-mixed, liquid casting resin into the mold containing the test pieces, again letting the air into the chamber, lifting the test pieces out of the casting resin and allowing the excess resin to drip from the test pieces. After that, they are placed in a mold cavity together with the test pieces with a pulverized resin, and applying pressure and heat to the mold cavity for a predetermined period of time, whereupon the test body is ready to be taken out and lapped.
