In today’s modern and highly competitive world, the quality of products as well as the quality in maintenance is of great importance. For that, the involvement of customers is very necessary. To convert these customers’ vague languages into technical data, a tool called Quality Function Deployment (QFD) is available in Total Quality Management (TQM). But in order to have quality in maintenance, no such tools or techniques are not available in Total Productive Maintenance (TPM) model. So, a model called Maintenance Quality Function Deployment (MQFD) was developed by incorporating TQM with TPM. Model study was carried out in a food industry; especially in an ice cream industry and suggested action plans for the implementation process for the quality enhancement was done through this study. Details about the machineries involved in the making of the food have been collected and processed for TPM parameter calculations. In food industry the MQFD model is not implemented yet. So, a model study in the food industry is very much useful especially in an ice cream industry due to the fact that, it is one among the most consumed food product all over the world.

Hybrid composites are formed by incorporating more than one reinforcement into the parent alloy and these are considered to be one of the significant materials used for aerospace, automobile, defence applications. Even nano hybrid composites are also evolving as materials to be considered with prominence. Aluminum metal matrix hybrid composites especially Al7075 hybrid composites are known for superior strength to weight ratio and good wear resistance, that's why those are considered as most useful materials in the field of mechanical applications. Ease of manufacturing, low cost of production paved the way for aluminum hybrid composites to emerge itself in to one of the potential material for future applications in aerospace, automobile, defence sectors. In order to develop aluminum hybrid composites several reinforcements were been added along with the metal matrix. Reinforcements enhance the mechanical, physical and micro structural characteristics of the hybrid composites. Mechanical properties would get enhance with varied wt % of reinforcements. This article provides an overview on recent developments on aluminum metal matrix hybrid composites.

In the present study Aluminum 6063 as the matrix and with Zirconium dibromide and Aluminum oxide as the reinforcement particle Metal Matrix surface composites were fabricated by friction stir processing. By the addition of reinforcements such as Zirconium Dibromide and Aluminum Oxide used as the strengthening agents during FSP process certainly made the MMC more wear resistant and harder than the base matrix. The effect of varying reinforcement percentage on the Mechanical wear and microstructure properties were studied. The Micro hardness showed an increasing trend in the nugget zone. The wear rate decrease with increase in volume percentage of hybrid reinforcement. FESEM images of the samples displayed uniform distribution of the particle in the matrix. And also reiterated the formation of hybrid particles.
