“…For instance, the osseointegration of titanium-based implants is generally improved by increasing the surface roughness of the implant [1,2]. However, a highly rough surface layer potentially deteriorates the corrosion resistance [3,4] and fatigue strength [5] of metallic biomaterials and biomedical implants and also increases the susceptibility of such materials to bacterial adhesion [6]. Therefore, control of the surface morphology and roughness of metallic implants should be carried out throughout their manufacturing process to maintain their functionality and service lifetime.…”

All blasting treatments with various blasting particles increased the roughness and hardness of the steel surface.  The roughest stainless steel surface was achieved by the slag ball-blasting treatment, but shot-blasting produced the stainless steel with the hardest surface and the thickest hard subsurface layer.  The physical properties and surface morphology of the particles or shot used in the blasting treatment are critical parameters in determining the surface characteristics of blasted stainless steel.

“…Однако их существенным недостатком являются низкие прочностные свойства, которые не улучшаются проведением термической обработки. Перспективным направлением деформационного упрочнения аустенит-ных сталей является применение таких современных методов поверхностного пластического деформирова-ния, как обработка SMAT (surface mechanical attrition treatment) -ультразвуковая обработка шариками в ва-кууме [1], дробеструйная обработка [2; 3], ультразвуко-вая ковка в вакууме [4] и ударная обработка бойками [5], пескоструйная обработка [6] и др. Упрочнение аус-тенитных сталей за счет сильного измельчения зерна наблюдается также при фрикционной обработке с пе-ремешиванием [7].…”

НАНОСТРУКТУРИРУЮЩИЕ КОМБИНИРОВАННЫЕ ФРИКЦИОННО-ТЕРМИЧЕСКИЕ ОБРАБОТКИ АУСТЕНИТНОЙ СТАЛИ 12Х18Н10ТКлючевые слова: аустенитная нержавеющая сталь; фрикционная обработка; нанокристаллическая структура; мартенсит деформации; деформационно-термическая обработка.Аннотация: Коррозионностойкие аустенитные хромоникелевые стали обладают низкими прочностными свой-ствами, которые не могут быть улучшены термической обработкой. Использование фрикционной обработки в качестве финишной операции позволяет обеспечить повышенную износостойкость, эффективное деформацион-ное упрочнение и высокое качество обрабатываемой поверхности стали 12Х18Н10Т. При эксплуатации и на ста-дии технологических операций изделия из аустенитной стали могут быть подвержены термическому воздействию. В настоящей работе с использованием методов просвечивающей электронной микроскопии, рентгеноструктурно-го анализа и измерения микротвердости изучено влияние нагрева в диапазоне температур 100-750 °С на струк-турно-фазовое состояние и микротвердость стали 12Х18Н10Т, подвергнутой фрикционной обработке, а также рассмотрены возможности упрочнения метастабильной аустенитной стали комбинированными фрикционно-термическими обработками. Установлено, что при фрикционной обработке в поверхностном слое стали возникает 65 об. % α'-мартенсита деформации, а микротвердость возрастает до HV 0,025=690. Двухчасовой отжиг при 450 °С обеспечивает сохранение в структуре 60 об. % α'-фазы и дополнительное повышение твердости поверхно-сти до HV 0,025=900 за счет выделения из мартенсита деформации наноразмерных карбидов Cr 23 C 6 и упрочнения ими нано-и субмикрокристаллических мартенситно-аустенитных структур, сформированных в поверхностном слое стали фрикционной обработкой. В результате нагрева до 650 °С на поверхности стали образуется аустенит-ная субмикро-и нанокристаллическая структура с твердостью HV 0,025=630, превышающей исходную твердость аустенитной стали в закаленном состоянии почти в 3 раза. На основании полученных результатов предложены два режима наноструктурирующих комбинированных деформационно-термических обработок, которые включают фрикционную обработку и последующие отжиги при температурах 450 и 650 °С.

Laser shock processing (LSP) is increasingly applied as an effective technology for the improvement of metallic materials mechanical properties in different types of components as a means of enhancement of their mechanical behavior. As reported in the literature, a main effect resulting from the application of the LSP technique consists on the generation of relatively deep compression residual stresses field into metallic alloy pieces allowing the life improvement of the treated specimens against wear, crack growth and stress corrosion cracking. Additional results accomplished by the authors in the line of practical development of the LSP technique at an experimental level (aiming its integral assessment from an interrelated theoretical and experimental point of view) are presented in this paper. Concretely, experimental results on the residual stress profiles and associated mechanical properties modification successfully reached in typical materials under different LSP irradiation conditions are presented along with a practical correlated analysis on the protective character of the residual stress profiles obtained under different irradiation strategies. In this case, the specific behavior of a widely used material in high reliability components (especially in nuclear and biomedical applications) as AISI 316L is analyzed, the effect of possible "in-service" thermal conditions on the relaxation of the LSP effects being specifically characterized. Keywords:Laser Shock Processing, Residual Stresses, Mechanical Behaviour, Fatigue Life Enhancement, Thermal Stability and Relaxation. INTRODUCTIONLaser shock processing (LSP) is increasingly applied as an effective technology for the improvement of metallic materials mechanical properties in different types of components as a means of enhancement of their corrosion and fatigue life behavior. Specially wear resistance, stress corrosion cracking susceptibility and crack propagation rate seem to be material properties specially improved by LSP treatments [1][2][3][4].Although the technique was initially developed for the improvement of the fatigue cracking resistance of materials used in the aeronautic applications (specifically Aluminum alloys), Titanium alloys and different types of stainless steels are being extensively investigated in the frame of different areas of application, especially the aerospatial sector itself but also in the nuclear, automotive and biomedical sectors on the basis of the commercial availability of new powerful laser sources able to provide intensities exceeding the GW/cm 2 level [5][6][7][8][9][10].In this paper, the special case of stainless steels and, more particularly, AISI 316L, is considered in view of the important number of applications of this material both in the energy sector (derived from its excellent corrosion resistant properties compatible with very convenient hot deformation (creep) resistance and good electron beam and laser weldability [11][12]) and its very promising applicability in the biomedical sector as structu...
