DIN 1.4110 martensitic stainless steel is largely used in the cutlery industry due to its high corrosion resistance associated with high mechanical resistance. However, when this material works under corrosion and wear conditions at the same time, their synergistic effect can accelerate the degradation process of the alloy. Cryogenic heat treatments have been proposed to improve the dimensional stability and mechanical properties, since they minimize the amount of retained austenite. The aim of this work is to study the effect of deep cryogenic heat treatment at -80 ºC and at -196 ºC on the corrosion resistance and tribocorrosion behavior of DIN 1.4110 martensitic stainless steel. The microstructure, hardness, corrosion resistance and tribocorrosion behavior were evaluated. Although the heat-treated samples presented higher hardness and lower corrosion current density (i corr ) compared to samples in spheroidized condition, their material removal under tribocorrosion conditions increased, which demonstrated the synergy between corrosion and wear.

Introduction: The mechanical properties and corrosion resistance of a material are dependent on its microstructure and can be modifi ed by phase transformation. When a phase transformation occurs in a material it usually forms at least one new phase, with physical-chemical characteristics that differ from the original phase. Moreover, most phase transformations do not occur instantly. This paper presents an evaluation of the phase transformation of martensitic stainless steels ASTM 420A and ASTM 440C when submitted to different thermal processes. Methods: Dilatometry tests were performed with several continuous heating and cooling rates in order to obtain the profi les of the continuous heating transformation (CHT) and continuous cooling transformation (CCT) diagrams for these two types of steel. Also, the temperature ranges for the formation of the different phases (ferrite and carbides; ferrite; austenite and carbides; non-homogeneous and homogeneous austenite phases) were identifi ed. Rockwell hardness (HRC) tests were performed on all thermally treated steels. Anodic and cathodic potential dynamic polarization measurements were carried out through immersion in enzymatic detergent as an electrolyte for different samples submitted to the thermal processes in order to select the best routes for the heat treatment and to recommend steels for the manufacture of surgical tools. Results: The martensitic transformation temperature tends to increase with increasing temperature for the initiation of cooling. The 440C steel had a higher hardness value than the 420A steel at the austenitizing temperature of 1100 °C. Above the austenitizing temperature of 1100 °C, the material does not form martensite at the cooling rate used, which explains the sharp decline in the hardness values. Conclusion: The study reported herein achieved its proposed objectives, successfully investigating the issues and indicating solutions to the industrial problems addressed, which are frequently encountered in the manufacture of surgical instruments.

“…Para sabermos se o sistema está em equilíbrio, foi colocado um multímetro medindo a continuidade de corrente, quando o corpo de prova fica em equilíbrio temos a continuidade aberta, podendo ser ouvido por um apito sonoro emitido pelo multímetro. Conforme definido por PINEDO [24], o endurecimento secundário é causado pela precipitação de carbonetos do tipo M 3 C. Já a diminuição na dureza com o aumento na temperatura de revenimento está associado com a transformação do carboneto M 7 C 3 em M 23 C 6 , seguida de seu coalescimento [24,25].…”

O objetivo deste trabalho é a construção de um dispositivo para a realização de ensaios de micro desgaste abrasivo por esfera fixa. O contato abrasivo é realizado por uma esfera de aço AISI 52100, a qual é presa num eixo que gira com grande precisão, com ajuda de um motor, em relação a uma amostra plana que se manterá estacionária. A carga normal de ensaio é aplicada através de ajustes de peso no suporte pivotado do corpo de prova, a qual pode ser variada a cada ensaio realizado. Este dispositivo foi utilizado para a determinação da resistência ao desgaste abrasivo e da eficácia de tratamentos de superfície utilizados em peças que sofrem este tipo de solicitação em serviço, além de utilizá-lo para estudar novos produtos desenvolvidos para o aumento de resistência ao desgaste de superfícies. Foi avaliada a resistência ao microdesgaste abrasivo de aço AISI 420 temperado e revenido. Observou-se que o aumento da dureza do material tratado aumentou a resistência ao desgaste abrasivo quando comparado com o material sem tratamento térmico.Palavras-chave: desgaste microabrasivo, esfera fixa, aço AISI 420, configuração experimental. ABSTRACTThe abrasive microwear testing has been the subject of a significant amount of research in recent years, when its potential to evaluate the behaviour of thin coating became relevant. The aim of this work is to build a apparatus for abrasive microwear testing by rotating sphere. The abrasive contact is performed by a AISI 52100 steel ball which rotates, with great accuracy with the help of an electric motor, in relation to a flat sample that will remain stationary. The normal load is applied by weight adjustments in the support of the test specimen, which can be varied for each performed test. This device was used to determine the abrasive wear resistance and effectiveness of surface treatments used in parts that undergo this kind of requirement in service, and also for studying new products developed for increasing the wear resistance of surfaces. The microwear resistance of the quenched and tempered AISI 420 steel was evaluated. It was observed that increasing the hardness of the treated material produced an increased wear resistance when compared with untreated material Keywords: microabrasive wear, rotating sphere, stainless steel AISI 420, experimental setup.
