WebApr 11, 2024 · The relationship between surface morphologies and the formation of pores was discussed. It reveals that the inter-layer printing on these surface defects caused by unreasonable laser power could increase the possibility of inside pore defects and reduce the density of specimens. WebCrystallization pressure arises when salts precipitate in the pores of stone or concrete. If the pore liquid is supersaturated, the crystal grows toward the pore wall, but does not make direct contact, because of repulsive disjoining pressure. fitted women\u0027s shirts button down
