QUESTÃO 1
É bastante antiga a preocupação do homem em obter metais resistentes e de qualidade.
Os romanos descobriram que o ferro se tornava mais duro quando aquecido durante
longo tempo em um leito de carvão vegetal, depois resfriado e, em seguida, mergulhado
em uma salmoura. Esse procedimento pode ser considerado a primeira forma de
tratamento térmico, pois permitia a fabricação de armas mais duras e mais resistentes.
Contudo, foram necessários muitos anos até o homem aprender a lidar de modo mais
eficiente com o calor e com os processos de resfriamento para tratar adequadamente os
metais. Considerando os tratamentos de TEMPERA, REVESTIMENTO,
REVENIMENTO e RECOZIMENTO, faça um texto apresentando as principais
características de cada um, contendo suas particularidades e temperaturas de trabalho.
