Therefore Tribology is defi ned as “ a science which stud- ies surfaces moving one compared to the other “ and also a fi eld of science studying lubrication, friction, and wear. This book aims to recapitulate old informations available and brings new informations that are with the fashion research on an atomic and nanometric scale in various fi elds by introducing several mathematical models to measure some parameters character- izing metals like the hydrodynamic elasticity coeffi cient, hardness, lubricant viscosity, viscosity coeffi cient, tensile strength It uses measurement techniques very devel- oped and nondestructive such as the optical and thermal methods like those used with chapters I, II. The principal distinction of this book is that it brings practical manners to model and to optimize the cu ing process using various parameters and diff erent techniques, namely, using water of high-velocity stream, tool with diff erent form and radius, the cu ing temperature eff ect, that can be measured with suffi cient accuracy not only at a research lab and also with a theoretical forecast. Therefore this book aims to minimize and eliminate the losses resulting from surfaces friction and wear which leads to a greater machining effi ciency and to a be er execu- tion, fewer breakdowns and a signifi cant saving. A great part is devoted to lubrication, of which the goal is to fi nd the famous techniques using solid and liquid lubricant fi lms applied for giving super low friction coeffi cients and improving the lubricant properties on surfaces. To recapitulate the book contains twenty three chapters which can be arranged in four sections entitled as follows: • Tribology of Thin Layers • Tribology in cu ing • Tribology and low friction • Tribology and Lubrication The sessions which are quoted before and their contents are enumerated and devel- oped below: X Preface Part 1 Tribology of Thin Layers CHAPTER 1 STUDY OF CRALN MULTILAYRED THIN FILMS. This chapter stipulates that the characterizations microstructural, morphological and physicochemical of a various multi-layer coatings deposited on surface are essential, of which the objective is it to connect the mechanical properties of these deposits to their macroscopic study like the forces of adhesion and microscopic like the pores surface and the cells sizes by using methods of optic and thermal characterizations like the AFM and the PTD technique. CHAPTER 2 OPTICAL CHARACTERIZATION OF ELASTOHYDRODYNAMIC LUBRI- CATION PRESSURE WITH SURFACE PLASMON RESONANCE This chapter completes recent advances of optical techniques for Elastohydrodynamic lubrication (EHL) studies and reports a recent application of surface plasmon reso- nance (SPR) sensing for the imaging of EHL point contact. A nondestructive technique based on the interference of two luminous rays, one collimated beam incidents and the other refl ects on the sensing surface at the resonance angle (~65°). A er enlargement the SPR image is further processed by an image analysis program for two dimensional Hue profi le extraction and processing and using an experimental calibration curve, the Hue profi le is further converted into corresponding refractive index distribution. Finally, the map of SPR resonance minimum is converted to corresponding RI distribu- tion with the help of a calibration curve it could noticed that only a small increase in refractive index is found in the outermost region of the dimple, which corresponds to the contact zone between the steel ball and the glass surface. CHAPTER 3 TRIBOLOGICAL PROPERTIES OF FLUORINATED AMORPHOUS CAR- BON THIN FILMS In this chapter the atomic fl at layers on surface samples are manufactured with very sig- nifi cant tribological properties and which are used for signifi cant applications such as hard drive disk coating. Among the deposition it shows the importance of the technique known in the literature as diamond-like carbon (DLC), which can only be obtained at conditions far away from equilibrium, and so it is not spontaneously found in nature. The control of the growth parameters broadens the fi eld of microstructures and, in par- allel, the properties of this material, which can only be synthesized in thin fi lm form. The fastest growing market for DLC simplify the manufacture of multilayers tribologi- cal coatings, this coating it implanted with protective fi lms, which can reduce corrosion and wear, may extend the lifetime of implants by preventing or alleviating the afore- mentioned issues. The friction coeffi cient of the sample depends to the etching dura- tion it varies from 13% for 15 min to 26% for 30 min this variation may be ascribed to the trapping eff ect of the pits defi ned by the micro-pillars that appears on the surface. CHAPTER 4 DEPOSITION AND TRIBOLOGY OF CARBON AND BORON NITRIDE NANOPERIOD MULTILAYER HARD AND SOLID LUBRICATING FILMS The aim of this chapter is focused on developing a new solid lubricant fi lm with an ex- tremely low friction which usual simple fi lm and mixed fi lm material lacked of carbon [...]... 51. 8 4.2 42.9 1, 2 15 00 0 .1 0 .14 50.8 4 43 .1 1 .17 300 0 .12 0 .16 50.5 4.7 42.5 1. 18 300 0 .11 0 .15 52 5 41. 3 1. 2 15 00 0 .13 0 .15 49.7 4.9 43.6 1. 18 256 0 .12 0 .16 50 .1 4.2 44.5 1. 17 356 0.09 0 .13 400 300 200 Cr( 220) Substrat CrN( 311 ) h-AlN Intensité 500 PVD1: (Cr/CrN/CrAlN)Pt PVD4: (CrN/CrAlN)Pt AISI 414 0 CrN( 200) 600 Cr2N( 11 1) 700 CrN( 11 1) h- AlN Table 1 Chemical composition and topography CrN ( 11 1)... 8 10 12 14 16 18 1/ 2 Square root modulation frequency (Hz ) (b) 25 0,8 0,7 CrAlN/CrN/Cr 0,6 Experimental Theoretical curve -1 -1 -4 2 -1 K1=93,9 W K ; D1=0,79 .10 m s m 0,5 -1 -1 -4 Phase (degree) 30 0,9 Normalized amplitude 1, 0 -1 -1 15 10 -4 CrAlN/CrN/Cr Experimental Theoretical curve -1 -1 -4 2 -1 K1=93,9W K ; D1=0,79 .10 m s m -1 -1 -4 2 -1 K2 =11 W K ; D2=0,23 .10 m s m 2 -1 K2 =11 W K ; D2=0,23 .10 ... frequency (Hz ) (a) 1, 0 CrN/Cr Experimental Theoretical curve 35 30 -1 0,7 CrN/Cr 0,6 Experimental Theoretical curve 0,5 -1 -1 -4 2 -1 K1=93,9 W K ; D1=0,79 .10 m s m -1 -1 -4 2 -1 K2 =11 W K ; D2=0,23 .10 m s m 0,4 -1 -4 2 -1 m K1=93,9 W K ; D1=0,79 .10 m s 0,8 Phase (degree) Normalized amplitude 0,9 -1 -1 -4 2 -1 K2 =11 W K ; D2=0,23 .10 m s m 25 20 15 10 5 0,3 4 6 8 10 12 14 16 18 1/ 2 Square root modulation... n -l n -1 -l i : T0 = ⎡( (1 + b ) η 4 eσ 1 l1 − (1 − b )η2 e −σ 1 l1 )En + (r1 − b ) e −α 1 l1 E1 ⎤ ⎡ (1 − b ) 1 e −σ 1 l1 − (1 + b ) η 3 eσ 1 l1 ⎤ ⎣ ⎦ ⎣ ⎦ With Ei = αi 2K i (α i2 − σ i2 ) , σ i = (1 + j ) π f Di , b = K bσ b K 1 1 , g= K fσ f K nσ n et r1 = 1 1 and 1 , η2 , η3 , η 4 are constant whose expressions depend on thermal properties and numbers of layers [17 ] 12 New Tribological Ways 2.3... different multi-layer 13 Study of CrAlN Multilayred Thin Films 40 1, 0 Cr Experimental Theoretical curve 30 0,8 0,6 Phase (degree) Normalized amplitude 35 Cr Experimental Theoretical curve 0,4 -1 -1 -4 2 -1 25 20 15 10 -1 -4 2 -1 K1=93,9 W.m K ; D1=0,79 .10 m s 2 -1 K1=93,9 W.m K ; D1=0,79 .10 m s 5 2 4 6 8 10 12 14 16 18 1/ 2 Square root modulation frequency (Hz ) 4 6 8 10 12 14 16 18 1/ 2 Square root modulation...
