“…(Distributions of the matter pressure, density and mass velocity for these two cases are given in Ref. In the first case, the shock arrives on the back side of the target earlier, although the nature of damage to the shield is similar in both cases and obeys the semi-empirical formula for the hole diameter D in the shield as a function of the projectile velocity up (in km/s) [12]: In the case of high-velocity impact, the maximum pressure P, , is close to the scaling calculation, but in the case of HPIB the difference between the calculation and scaling estimate of Pmax is up to 50% (dots in Fig.…”

“…Os filmes de PPy apresentam baixa rugosidade, flexibilidade, propriedades mecânicas boas e baixo custo de produção (16) . Todas essas características associadas à não toxicidade dos polímeros, torna-o vantajoso para ser utilizado como revestimento protetivo contra corrosão na liga de alumínio aeronáutico 2024-T3 (17)(18) . A polimerização eletroquímica direta de pirrol em eletrodos de metais ativos, como as ligas de alumínio, é complicada devido à oxidação do metal, que concorre com a oxidação do monômero, podendo inibir o crescimento do polímero ou reduzir a aderência do polímero ao metal (19,20) .…”
