Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The oil and gas industry faces extremely aggressive environments, as some oil extraction fields in Brazil are highly acidic due to the presence of chlorides, sulphur compounds and oxygenates. As a result, during the high-temperature refining stage, the corrosion rate increases in extraction equipment, pipes, connections, valves, etc. Because of this, it is necessary to use materials with high resistance to corrosion and toughness, properties present in various types of stainless steel. Liquid nitriding is one of the processes used to generate surface hardening, high resistance to wear, fatigue and corrosion in metallic materials through the atomic diffusion of nitrogen on the surface of the material. This thermochemical treatment consists of immersing the workpiece in a medium of molten salts rich in nitrogen at temperatures of 500 to 570ºC. The aim of this work was to analyze the liquid nitriding process on 17-4 PH stainless steel and to characterize the nitrided layer and the microstructure of the substrate adjacent to the deposition using microhardness, optical microscopy and scanning electron microscopy techniques. 68 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Przemys¿ naftowy i gazowy stoi w obliczu niezwykle agresywnych ¿rodowisk, poniewä niektóre pola wydobywcze ropy naftowej w Brazylii s¿ bardzo kwäne ze wzgl¿du na obecno¿¿ chlorków, zwi¿zków siarki i tlenków. W rezultacie na etapie rafinacji w wysokiej temperaturze wzrasta szybko¿¿ korozji sprz¿tu wydobywczego, rur, armatury, zaworów itp. Z tego powodu konieczne jest stosowanie materiäów o wysokiej odporno¿ci na korozj¿ i wytrzymäo¿ci, w¿äciwo¿ci wyst¿puj¿cych w ró¿nych rodzajach stali nierdzewnej. Azotowanie ciek¿e jest jednym z procesów stosowanych do generowania utwardzania powierzchniowego, wysokiej odporno¿ci na zu¿ycie, zm¿czenie i korozj¿ w materiäach metalicznych poprzez dyfuzj¿ atomow¿ azotu na powierzchni materiäu. Ta obróbka termochemiczna polega na zanurzeniu przedmiotu obrabianego w ¿rodowisku stopionych soli bogatych w azot w temperaturach od 500 do 570ºC. Celem niniejszej pracy by¿a analiza procesu azotowania ciek¿ego na stali nierdzewnej 17-4 PH oraz scharakteryzowanie warstwy azotowanej i mikrostruktury pod¿o¿a przylegaj¿cego do osadzania za pomoc¿ mikrotwardo¿ci, mikroskopii optycznej i skaningowej mikroskopii elektronowej. 68 pp. Polnisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -L'industria petrolifera e del gas si trova ad affrontare ambienti estremamente aggressivi, in quanto alcuni giacimenti di estrazione del petrolio in Brasile sono altamente acidi a causa della presenza di cloruri, composti di zolfo e ossigenati. Di conseguenza, durante la fase di raffinazione ad alta temperatura, il tasso di corrosione aumenta nelle attrezzature di estrazione, nei tubi, nei raccordi, nelle valvole, ecc. Per questo motivo, è necessario utilizzare materiali con elevata resistenza alla corrosione e tenacità, proprietà presenti in diversi tipi di acciaio inossidabile. La nitrurazione liquida è uno dei processi utilizzati per generare indurimento superficiale, elevata resistenza all'usura, alla fatica e alla corrosione nei materiali metallici attraverso la diffusione atomica dell'azoto sulla superficie del materiale. Questo trattamento termochimico consiste nell'immergere il pezzo in un mezzo di sali fusi ricchi di azoto a temperature comprese tra 500 e 570ºC. Lo scopo di questo lavoro è stato quello di analizzare il processo di nitrurazione liquida su acciaio inossidabile 17-4 PH e di caratterizzare lo strato nitrurato e la microstruttura del substrato adiacente alla deposizione utilizzando tecniche di microdurezza, microscopia ottica e microscopia elettronica a scansione. 68 pp. Italienisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A indústria de petróleo e gás enfrenta ambientes extremamente agressivos, pois alguns campos de extração de petróleo no Brasil apresentam uma elevada acidez, devido à presença de cloretos, compostos sulfurados e oxigenados. Em virtude disso, na etapa de refino em altas temperaturas, a taxa de corrosão aumenta nos equipamentos de extração, nas tubulações, conexões, válvulas, etc. Devido a isso, é necessário a utilização de materiais com elevadas resistências à corrosão e à tenacidade, propriedades presentes nos diversos tipos de aços inoxidáveis. A nitretação líquida é um dos processos utilizados para gerar endurecimento superficial, alta resistência ao desgaste, à fadiga e a corrosão em materiais metálicos através da difusão atômica de nitrogênio na superfície do material. Este tratamento termoquímico consiste na imersão da peça em meio de sais fundidos ricos em nitrogênio em temperaturas de 500 a 570ºC. Este trabalho teve como objetivo analisar o processo de nitretação líquida no aço inoxidável 17-4 PH e caracterizar a camada nitretada e a microestrutura do substrato adjacente a deposição utilizando técnicas de microdureza, microscopia óptica e microscopia eletrônica de varredura. 80 pp. Portugiesisch.
