Les procédés d’élaboration de Composites à Matrice Céramique (CMC) utilisés aujourd’hui à l’échelle industrielle sont longs et par conséquent coûteux. Dans ce contexte, le procédé de densification rapide ou procédé de caléfaction, jusque-là essentiellement connu pour l’élaboration de carbone, permettant de réduire considérablement les durées d’élaboration, apparaît intéressant. Cette étude est axée sur le développement du procédé de caléfaction dans le but d’élaborer des carbures, matériaux connus pour leurs bonnes propriétés à haute température, et plus particulièrement du carbure de silicium (SiC). Dans cet objectif, un équipement de laboratoire, le mini-kalamazoo, a été mis au point, adapté et instrumenté de manière à répondre aux besoins de l’étude. Les premiers essais ont été réalisés au moyen de méthyltrichlorosilane (MTS), précurseur largement connu pour la CVD/CVI du SiC. Les analyses des dépôts formés ont montré la présence de SiC mais aussi celle de carbone. Dans quelques cas spécifiques, du SiC pur peut être formé localement en début de caléfaction. Mis à part ces conditions particulières, l’utilisation de MTS pur en tant que précurseur conduit à la présence inéluctable de carbone libre dans le dépôt de SiC. Plusieurs voies d’amélioration ont alors été proposées et testées pour pallier cet excès de carbone. Certaines d’entre elles se sont avérées efficaces et prometteuses, en particulier, l’utilisation d’un mélange de MTS et d’un précurseur de silicium non carboné et l’utilisation de précurseurs de SiC non chlorés, le CVD 4000 et l’hexaméthyldisilane. Les vitesses de croissance de dépôt sont largement supérieures avec le procédé de caléfaction qu’avec les moyens d’élaboration aujourd’hui employés. L’ensemble des résultats obtenus valide l’intérêt de la caléfaction en tant que procédé d’élaboration du SiC et de nouveaux matériaux de type carbure. / The current Ceramic Matrix Composites (CMC) manufacturing processes used at the industrial scale are slow and consequently expensive. In light of this, the fast densification process, also called the film-boiling process, essentially known to produce carbon deposit up to now, reduces significantly the processing time which seems to be promising. This study was focused on the film-boiling process development in order to manufacture carbides which are materials with good properties at high temperature, and especially to synthetize silicon carbide (SiC). In this aim, a laboratory-made equipment was developed, set-up and adapted to the needs of our study. The first tests were done with the methyltrichlorosilane (MTS), precursor widely used for SiC CVD/CVI. Characterizations of the deposits showed the formation of SiC but also the occurrence of carbon. Pure SiC can be locally obtained at the beginning of the film-boiling process in some specific experimental conditions. For most of the experiments, the use of pure MTS as precursor leads inevitably to the formation of free carbon in the SiC deposit. Several improvement routes were proposed and tested to remove this carbon excess. Some of the efficient and promising routes have consisted in the use of MTS mixed with a silicon precursor free of carbon and the use of two non-chlorinated SiC precursors, CVD 4000 liquid precursor and hexamethyldisilane. The deposit growth rates were significantly superior with the film-boiling process compared to the classical processes. All the data show that the film-boiling process is promising for the manufacturing of SiC and new carbide materials.

The purpose of the study was to analyze the perceptions of teacher trainees, first and second year practicing teachers, college educators, and public school administrators regarding the effectiveness of the undergraduate teacher preparation programs at Ball State University, Muncie, Indiana; and Western Michigan University, Kalamazoo, Michigan. The analysis of the programs may possibly be applied to teacher preparation programs in Sierra Leone, West Africa.In the study an attempt was made to discover new concepts and practices and potential approaches that would strengthen the undergraduate teacher preparation programs at Ball State University and Western Michigan University. To secure evidence concerning the existing conditions, the following population was randomly selected.(a) Two hundred teacher trainees, two hundred first and second year practicing teachers, fifty-five college educators, and fifty-five public school administrators from Ball State University.(b) Two hundred teacher trainees, two hundred first and second year practicing teachers, fifty college educators, and fifty public school administrators from Western Michigan University.The questionnaire method for obtaining data was determined to be the proper technique and some direct observation of each program was also made. The sampling included every third person in all four main groups. Based on the number of returned and usable questionnaires,(a) the perceptions of one hundred and sixty-five teacher trainees, one hundred first and second year practicing teachers, fifty-one college educators, and fifty-four public school administrators from Ball State University were tabulated, computed, described and analyzed.(b) the perceptions of seventy-nine teacher trainees, forty-eight first and second year practicing teachers, twenty-two college educators and eighteen public school administrators from Western Michigan University were tabulated, computed, described and analyzed.Significant variables also included sex, professional experience, and teaching/administrative positions.The results of the findings revealed that despite the varied expectations of what constitutes an effective teacher preparation program, a high degree of consensus was obtained among the respondents that most of the activities and practices carried out at Ball State University and Western Michigan University were effective. In most instances, the respondents indicated the items as outstanding and/or above average.Supportive and favorable remarks were expressed for specific programs such as special education programs for the handicapped and the disabled; the TOD programs; the multi-cultural programs; and the adult and continuing education program at Ball State University.Based on the findings of the study the following conclusions were made:1. The instructional programs in terms of the curricular content and instructional strategies or modules were effective.2. The supervisory and other related activities such as classroom observation, testing, grading, communication patterns in the pre-student and student teaching in-service programs were effective.3. The personal relationship between the teaching staff and the students was effective.4. The college policies and administrative procedures were effective.5. The motivation, rewards, and sanctions provided forpersonal and institutional growth were effective.6. The evaluative process in terms of staff and studentratings was effective and consistent in general.7. The total evaluative program in terms of the mechanisms of adaptability and flexibility was effective.8. The teaching, research and public services providedwere effective.Areas of concern that may need some examination were general studies; micro-teaching and laboratory experience; student advising in the area of course selection; the selection process in the pre-student and student teaching stages; activities relating to sensitivity/group dynamics; understanding the relationship with the opposite sexes; learning and respecting other cultures; student involvement in the selection of courses; and, communication patterns between college staff, students and teaching staff and the administrative staff.
