Abstract:

No presente trabalho são relatados os resultados obtidos através de tratamentos térmicos e de ensaios de abrasão, em uma liga de ferro fundido branco alto cromo contendo nióbio, obtida por fundição. Os tratamentos térmicos de têmpera foram efetuados nas temperaturas de 950, 1000, 1050 e 1100ºC e o meio de resfriamento utilizado foi o ar soprado. Os tratamentos de revenidos foram efetuados nas temperaturas de 450, 500 e 550ºC. A liga no estado termicamente tratado foi comparada, nos ensaios de abrasão, com ligas comerciais utilizadas como revestimento duro por soldagem em peças desgastadas. Os

В настоящее время одной из проблем машиностроительного производства является повышение качества и производительности финишного этапа изготовления деталей. Особенные трудности вызывают сложнопрофильные детали, требующие точного позиционирования инструмента по отношению к обрабатываемой поверхности, и тонкостенные детали, которые нельзя подвергать высокому силовому давлению. Финишная обработка таких деталей вызывает необходимость применения или дорогостоящего специального оборудования, или ручного труда различной степени тяжести, который к тому же является продолжительным и монотонным, и требует

Micro air abrasion is a new modern method for removing decay and old fillings. It is used a fine stream of aluminium oxide powder and compressed air. Micro air abrasion was discovered in 1940 in USA. Sandman’s unique patented whirl system and special hand pieces secure a unique precision and working condition of the aluminium oxide powder. Dentists can obtain optimal results using the unit with a working pressure between 1½ - 3 bars. In comparison, other systems are used pressure working area of 4 - 8 bars.
